Description

The Marconi Electronic Systems Chieftain Mk.10 Marksman (shortened to Chieftain Marksman) is a rank VI British self-propelled anti-aircraft vehicle with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.79 "Project X".

The Marksman looks like Chieftain tank hull with a giant boxy turret in the middle of it. The turret has a radar on the back of it and clearly visible handles with cannons on its front. The front has a distinctive double slope. There is no other such turret in-game and so it is very easy to identify.

Like the Falcon, the Marksman's role is hiding around the battlefield, shooting at planes and punishing unsuspecting ground opponents, however, it is much slower so it does its job from about kilometre away, or further if possible.

Radar allows it to have an aiming reticle against incoming planes in RB. The reticle works the same way as in AB, however, it doesn't say how far away the plane is.

Since Update 1.87 "Locked On", radar also allows you to lock your turret to follow a specific target (the one closest to your targeting reticle) and to see a "true" targeting reticle, which will guarantee a hit up to 3km range and, on some occasions even further, even if you don't have any modifications, unless the enemy aircraft changes course. It is very important to change the keybinding of the radar lock key (default "alt + f"), as radar won't reliably lock on to targets, due to "mouse pointer" mode from "alt" button.

If you want to use radar to specifically try and "find" a target that is too far away for you to see, you can try to stop radar dish by using "change radar search mode" (not bound by default) and specifically look towards the direction you expect them to come from (the enemy airfield, for example). If your turret happens to detect them, they will appear on your radar screen, and you can target them. However, the use of this option is severely limited due to the fact that planes rarely move in a straight line, so even if you try to snipe them from 4km range, it will likely result in a miss, so the default search mode is generally better.

You can snipe ATGM helicopters now. However, do not waste ammo on helicopters that move around a lot, even radar cannot predict their dodges from this far away.

The playstyle is much less aggressive than the Falcon; however, the APDS belt is no joke, as every shell in it can penetrate about 100 mm of armour up to 500 meters and up to 60 mm at 2,000 meters at 30°. As such, weaker side armour on most rank 5+ vehicles of all nations can be threatened by the Marksman from almost any range, and it only brings much more pain to light vehicles from afar. Only Soviet tanks have decent enough armour on nearly all vehicles to negate its firepower in optimal weapon range.

It may feel like the guns are similar to the Falcon's when you fire them but due to them being 35 mm you can tear off plane wings even in one hit, and you can hit them even with stock gun easily from 1.8 km range without wasting too much ammo. Guns have a convergence of about 1.5km (more or less, depending on "adjustments of fire" upgrade), which makes them better for leading targets, but also wasting some ammunition in process, and making vehicle weak at closer ranges.

Guns still overheat in 10 seconds and can put the Marksman out of fighting capability for half a minute. Luckily, it's hardly necessary to go trigger happy with the Marksman's accuracy and you can change belts to instantly unjam the cannons.

Even a glancing hit to a turret of powerful enough shell will annihilate SPAA immediately.

The Chieftain chassis is fairly well protected against frontal attacks by light vehicles. The turret protection, however, is not great - it will stop most heavy machine-gun fire at close range, but anything of high caliber could cause a hull break. Overall, tank feels almost like the FV4005 with slightly more armour on turret.

Do not show the lower front plate to the enemy's tanks, as it's considerably weaker. Despite having better armour for hull, the Marksman is extremely slow for it, so keeping the enemy away from this vehicle is the key to making the most of the armour it have, even though most opponents will only fire at its turret.

Generally, if turret doesn't break in a single hit, the crew is taken out in such order: Firstly the enemy does a precise shot at the bottom-left (vehicle's right) of the turret to take out the gunner, then fires at the opposite to take out tank commander. It's also easy to destroy Chieftain Marksman turret with chemical rounds. Turret may tank 20 mm autocannon shots, but only at about 1.2 km range, which is an acceptable duel range for the Marksman. Any non-stock combat SPAA's and light tanks, though, will breach it with no effort even from 3 km away.

Main armament

Marksman has an extremely fast turning turret, so any incoming plane or light vehicle can be targeted fast.

Guns converge at about 1.2 km range without "Adjustment of Fire" modification and about 1.8 km with it. This makes firing at close range enemy vehicles very impractical, due to low ammunition count. However, it's very convenient for firing at moving targets, including light tanks and jets, as the two separate autocannons increase the probability of a hit.

The guns can disable both tracks of the enemy vehicle at once at 300 m distance if facing the enemy's front. This allows you to escape and ask teammates to finish off the threat.

Since the guns are 35 mm, they also deal more damage than 30 mm of the previous generation SPAA, use the explosive ammo to destroy planes in about 1 to 2 hits, lightly armoured vehicles get destroyed in about 30 shots at worst.

Ammunition

Ammunition belts are split into 2: the main belt and secondary belt.

The Marksman can take 460 shells for the main belt and 40 for secondary, which is barely enough for one engagement. This may be insulting, but it's necessary for survival. Unlike the Falcon, when ammo for the main belt runs out, this could be reloaded at a capture point while the second belt of pure anti-air or anti-armour rounds can be used as self-defence.

Also, there won't be a need to reload a new belt once the ammo restocks is complete, so the Marksman is ready to fight quicker.

Note that the DM23 APDS belt can only be a secondary belt. This makes the decision about the secondary belt being fully anti-tank or fully anti-air ever more annoying and affecting your playstyle.

There is also a difference in effective range between normal belt and APDS belt. For some reason, AP-I shells can only fly up to 3km away and even radar will refuse to help aiming them past that range. This does not happen with APDS, allowing to snipe even as far as 5 km, at which range even radar itself is barely capable of keeping up the lock on.

You can only reload one belt at once. Your secondary belt rearms in about 5 seconds, while your main belt rearms for about 45 seconds. Thus, your playstyle is majorly dictated by how far from the capture point you are.

Use night vision to avoid hostile tanks or to fight them at close range at night. The image intensifier is not installed for gunner or commander, so be cautious when shifting between third person and other views during night.

While Chieftain Marksman gun convergence can allow it's user to fire at targets in 3-rd person view and still hit a target, you have to use sniper scope to increase accuracy of radar aim, but keep sensor guidance errors in mind during this.

Rely mostly on your radar when firing at night, but do not forget to check, if lock-on is stable, as it may wobble around the target at times.

Radars

The Chieftain Marksman is equipped with a Marconi S 400 search and tracking radar, mounted on top of the turret, at the rear. The radar system lacks track while scan but can track targets in a full 360° area around the turret (instead of just to the front of the turret). The tank often spawns with radar off, it is folded when powered down.

Usage in battles

Follow the team's push and take some nice fortified position with sight on the capture point, destroying any scout vehicles that attempt to get close while looking for planes. Conducting both actions at once is crucial to not only deny the enemy a recon point but also for self-preservation to keep the Marksman protected. Fighting at a distance will be best to minimize convergence distance to avoid wasting ammunition on the lead. Vertical traverse of cannons is almost instant, so that should not be a concern when shifting from ground to air target. As the main belt's ammo runs out, move closer to the capture point to rearm. With this tactic, use the secondary belt only for self-defence on the capture point, or if it's really necessary for a teammate's survival.

Alternatively, you could go straight for capture point defence and unload secondary belts onto every passing plane, light tank, SPAA and poorly armoured MBT, then immediately rearm. Since your guns convergence is 1-2km depending on upgrades, there is little chance that any vehicle which is travelling in a straight line can dodge your double cannon lead. However, don't expect to successfully push away medium tanks, if your belt isn't APDS, and it's very likely that the enemy's return fire will heavily damage or hull break you, as capture points rarely provide any cover, so move out and use your main belt, when forced to.

Using radar-assisted aim is advised since it's more accurate and can lead to hits at over 3km range. To conserve ammo, however, do not just blindly follow it, especially in arcade, as arcade mode aircraft tend to dodge direct shots - do some short bursts around it. If you are standing on a frontline, remember that Marksman is very tall and it is not rare for some tankers to get annoyed by your presence and try to shoot the radar off the turret, even if the turret itself is almost entirely behind cover and attack achieves nothing else, so try to move somewhere remotely safe if you are expecting an air raid.

In arcade mode your combat ability is severely limited, due to many maps being 2 x 2 km wide at best, so on such maps you could try to train your crew with very high "keen vision", then try to camp enemy base entrances across the map, using the fact that your shells have little penetration falloff over distance and slight armour angling. This would require great map knowledge, though. As soon as enemy planes or attack helicopters appear, destroy them.

On big maps in arcade mode, keep in mind, that every sniper tank on enemy team might try to shoot in your direction, as soon as they are done destroying medium tanks, or if hostile light tank "scout" you. It is very hard to snipe planes from spawn on such maps, so try to secure some "trench line" in form of a hill, which you can use to follow your team even under sniper fire. Snipe lightly armoured tanks back, if they expose themselves. Having high "keen vision" greatly helps at this as well.

Some enemies to be concerned about:

• Soviet tanks: Avoid them as much as possible. With the gun convergence and reduced movement speed, it will not be easy to defeat them in a duel, as their frontal armour is almost always impenetrable, even for APDS belt. Detrack them and communicate with teammates to finish them off. Sometimes their medium tank drivers are very arrogant and underestimate Marksman, due to how rarely it is spaded and do not immediately turn their frontal armour towards it, thinking that you cannot destroy them anyway - punish them by shredding their tank with APDS belt, or by firing AP belt into generally weak side-bottom part of their tank.
• Maus: It's invulnerable. Best not to show up in parts of that map it controls.
• Centauro: This is the epitome of all tanks Marksman wants to shoot at - it is mobile, can reach and flank your position in a minute and has scouting as well. Fortunately, it also has the armour of a light tank, so if you see it out of cover, drop your lock on and fire at it, before it hides away.
• Helicopters: While helicopters are slow and may look like an easy target, they can change direction of flight and throw off radar aim or try to drop altitude, avoiding shots from over two kilometres away, so keep checking where it is trying to turn or roll, instead of just firing at the radar aiming reticle. Also, due to Marksman cannon convergence, try to keep them away from you or spread shots horizontally, as it is not rare to only cut off weapon pylons off attack helicopter, but fail to actually disable its gunner/co-pilot, so if after critical hit on a helicopter or setting it on fire ATGM still flies directly at your SPAA, it is better to hide behind something. Rocket carpet bombing is also dangerous for Marksman due to turret being very big, so try to move out of the way of the main volley, if only a bit - a close miss of weak rockets should fail to penetrate chieftain hull. The radar will keep your aim true, so don't worry about accuracy during movement too much. After a certain point, helicopters acquire 8 km range ATGMs and outclass you entirely, which is when you have to swap to the next generation SPAA, especially in RB.

Radar makes hitting passive pilots extremely easy, and in Realistic Battle you can take them down with just 1 hit of explosive ammo. Even if it doesn't look like a fatal hit, it can eventually force plane to crash. In arcade mode radar guidance ensures you won't need to spend your entire ammunition trying to take down one bomber or ATGM helicopter.

Pros and cons

Pros:

• Guns produce a great effect upon shell contact on target, requiring only one or two hits to down a plane
• Can fire effectively at longer ranges than Falcon and has radar guidance on top of that
• Compared to Gepard and Type 87 has relatively easy time shooting down planes even without use of a sniper scope
• Secondary belts allow for safer rearms compared to Falcon and Vulcan
• Has a stable radar system with full 360° target tracking - it rarely ever needs to be manually locked on

Cons:

• Low mobility - it can't outrun most of its opponents and moving around the map at it's rank can be a challenge in itself
• LFP is a weak spot even for some light tanks, turret is lightly armoured and is a big target for rockets and other explosives - keeping 1.3 km distance is crucial when fighting light tanks and other SPAA
• Due to very tall profile it is an easy target, when compared to other SPAA of the rank. it is hard to never show it to medium tanks or SPG in order to avoid being hull broken
• The cannon's convergence makes the Marksman weaker in close combat, as it can only hit targets with one gun at short range
• Ammunition count is low, firing in 20-30 shot bursts is almost a must
• APDS ammo is now put into a separate belt, which may be inconvenient to use with a low ammunition capacity
• Slower rate of fire than other SPAA
• Radar system lacks track while scan and has relatively poor range
• Still does not have gunner night vision, although radar mostly compensates for that (can cause problems at pitch black maps of 9.0+)

History

With the development of more effective modern weapon systems, deployed from aircraft capable of flying at very high speeds and low altitudes, mobile ground troops were more susceptible to air attack than ever. The British Marconi Electronic Systems company came to the same conclusion during the early 1980s and began independently developing the Marksman project after realizing how little work was being done in the field of modern SPAA development. The concept of the Marksman project wasn't the development of an entirely new vehicle, but rather of a modern anti-air platform that could be fitted to a wide range of suitable military vehicles, even non-British ones. Naturally, the platform had to be capable of dealing with the most modern threats, such as high-speed attack aircraft and helicopters. In order to achieve this, Marconi engineers gave the Marksman a highly advanced radar detection and targeting system and paired it up with twin 35mm Oerlikon KDA cannons in a similar fashion as found on the German Flakpanzer Gepard.

The testing of the first construction prototype was done on the chassis of the Chinese Type 59 tank. This decision was primarily made in an effort to optimize the platform for use on similar Chinese machines in order to attract potential customers using Chinese vehicles. In 1984, further tests were conducted, only this time around, using chassis of British vehicles such as the Centurion, Chieftain and Challenger 1. However, in order to further increase the number of vehicles that could potentially fit the Marksman platform, Marconi developed several adapters that allowed the platform to be fitted on hulls with a turret ring diameter smaller or in excess of 1840mm. However, as even newer, more capable aircraft weapon systems were developed during the '80s which could easily destroy such SPAAs, the Marksman system became more or less obsolete before it was even deployed. Due to this, the primary expected customer - the British Armed Forces - didn't show any interest in adopting a conventional SPAA system, such as the Marksman. Only a limited number of Marksman systems was employed by the Finnish army on their ItPsv 90 SPAAs, which were retired from active service in 2010 and replaced with Leopard 2 Marksman conversions which are still in service today.
