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 giant boxy turret in 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 distinctive double slope. There is no other such turret in game and so it is very easy to identify.

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

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

Since "lock on" update radar also allows you to specifically lock your turret to follow specific target (the one closest to your targeting reticle) and to see "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 enemy plane or helicopter changes course. It's default keybind is alt+F, which is very important to bind to anything else (for example, override N button, used for statistics), otherwise radar won't pick up targets reliably, due to "mouse pointer" mode from "alt" button.

If you want to use radar to specifically try and "find" one 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 at direction you expect them to come from (enemy airfield, for example). If your turret will happen 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 fact, that planes rarely move in straight line, so even if you will try to snipe them from 4km range, that will likely result in a miss, so defaul mode is almost always 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 play style is much less aggressive than 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 2000 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 soviets have decent enough armour on nearly all vehicles to negate it's firepower in optimal weapon range.

It may feel like guns are similiar to falcon when you fire them but due to them being 35mm 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 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 marksman's accuracy and with marksman you can instantly change belts to unjam the cannons.

General info

Survivability and armour

The Chieftain chassis make this SPAA invulnerable to hull breaks and protects it fairly well against frontal attacks by light vehicles. The turret protection is not great, but it will stop most heavy machine gun fire at close range. It's 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, Marksman is extremely slow for it, so keeping the enemy away from this vehicle is the key to get all out of armour you have.

Vehicle can be taken out by attacking the turret: Firstly enemy does precise shot at bottom-left (vehicle's right) of turret to take out the gunner, then fires at the opposite to take out tank commander. It's also easy to destroy your turret with chemical rounds. Your turret may tank 20mm auto cannon shots, but only at about 1.2 km range, which is an acceptable duel range for marksman. Any non-stock combat SPAA's and light tanks, though, will breach it with no effort even from 3km away.

The speed of Marksman is very low. It barely can turn around and you can't use speed against enemy, due to poor hp/ton ratio.

If you keep moving forward without changing direction, you might eventually reach 40km/h on flat terrain.

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 "Adjustments 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 if two separate autocannons increase the probability of a hit.

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

Since the guns are 35 mm, they also deal more damage than 30 mm of 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.

Belt types:

Penetration statistics
Belt	Type of warhead	Penetration in mm @ 0° Angle of Attack
		10m	100m	500m	1000m	1500m	2000m
Default	API-T, HEI-T	67	64	52	39	30	23
DM11A1	API-Tx3, HEI-T	67	64	52	39	30	23
DM-13	HEI-Tx3, API-T	67	64	52	39	30	23
DM-23	APDS	112	110	101	90	71	62

Note: HEI-T does no damage to armoured targets, but critically damages planes.

Ammunition belts are split into 2: main one and secondary one.

The Marksman can take 460 shells for main belt and 40 for secondary, which is barely enough for 1 engagement. This may be insulting, but it's necessary for survival. Unlike Falcon, when ammo for the main belt runs out, this could be reloaded at capture point while the secondary belt of pure anti-air or anti-armor rounds that could be used as self-defense.

Also, there won't be a need to reload a new belt once the ammo restock is complete, so the Marksman is ready to fight quicker. The other thing with ammunition belts is that since APDS belt is now purely APDS. This makes decision about secondary belt being fully anti-tank or fully anti-air ever more annoying and affecting your playstyle.

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 capture point you are.

Usage in battles

Follow the team's push and take some nice fortified position with sight on the capture point, destroying any scout vehicle 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 a ground to air target.As main belt's ammo runs out, move closer to capture point for rearm. With this tactic, use secondary belt only for self defence on capture point, or if it's really necessary for teammate's survival.

Alternatively, you could go straight for capture point defence and unload secondary belts onto every passing by plane, light tank, SPAA and poorly armoured MBT, then immideately rearm. Since your guns convergence is 1-2km depending on upgrades, there is little chance any vehicle which is travelling in 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 enemy's return fire will heavily damage you, as capture points rarely provide any cover, so move out and use main belt, when forced to.

In arcade mode your combat ability is severely limited, due to maps being 2x2 km wide at best, so 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 from distance and slight armor angling. This would require great map knowledge, though. As soon as enemy planes or Attack helicopters appear, destroy them. Using radar-assisted aim is adviced (since it's more accurate and can lead to hits at over 3km range) to conserve ammo, however, do not just blindly follow it, as arcade mode aircrafts tend to dodge direct shots - do some short bursts around it.

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. Detrack them and communicate to the teammates to finish them off.
• Maus: It's invulnerable. Best to not show up in parts of map it controls.

Pros and cons

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 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:

• Guns produce 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.
• Chieftain hull offers good protection
• Secondary belts allow for safer rearms

Cons:

• Low mobility
• APDS ammo is now put into separate belt, which may be inconvenient to use with low ammunition capacity
• Slower rate of fire than other SPAA
• LFP is a weak spot
• Turret is lightly armoured and a big target
• Cannons convergence makes the Marksman weaker in close combat

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.
