Cupola	15 mm (3°)			13 mm

Notes:

• Suspension wheels and tracks are 15 mm thick, while torsion bars are 10 mm thick.
• Mudguards are 13 mm thick.

The Nb.Fz. has an even higher survivability than Panzer III/IV tanks at similar battle ratings because of its larger crew count and vehicle size. The armour thickness is actually rather thin, despite a very imposing look and a complex internal layout. It has six crew members: a driver, two machine gunners in small independent turrets, a gunner, a loader, and a commander in the main turret where both main guns are located. The front armour thickness ranges from just 13 mm to 20 mm, making it possible to immobilize it with heavy machine gun fire frontally.

The top speed of the Nb.Fz. is 28.5 km/h, which is slow for low-tier ranks. The power-to-weight ratio, on the other hand, is rather good at 11.9 hp/ton, giving it a very nice acceleration considering how large it is. But, this is relatively slow, so remember to stay in cover, because tank destroyers can destroy this vehicle's armour relatively quickly and easily. Another thing to keep in mind is the Neubaufahrzeug's terrible rotation. Pivoting on the spot is basically impossible, and it slows down a lot in turns. Be careful not to turn too much, or you will slow down and be an easy target.

The Neubaufahrzeug's main armament is the KwK37 cannon, which shoots APHE, penetrating up to 52 mm of armour, 80 mm penetration HEAT, and smoke rounds. Problem is, due to the current limitations of the game, it is impossible to take more than four different kinds of shells, and for multi-gun tanks, each gun can just pick two shells in its repertoire. So the practical combinations would be either APHE+HEAT, APHE+smoke, or HEAT+smoke.

The Neubaufahrzeug also has an additional second anti-tank gun in the main turret: a 37 mm KwK36, located to the left of the 75 mm cannon. This shoots either 47 mm penetration APHE or 86 mm penetration APCR rounds. It is the same decent gun as the Pz.III B and Pz.III E, but is best used as a backup to the 75 mm between reloads. It shoots at far higher muzzle velocity, so it is more suited to long-range engagements.

The Neubaufahrzeug also holds three small-calibre MG13 Dreyse machine guns, which are similar to the MG34 and use the same belts. At best, they're good for strafing flak trucks, but in practicality, they're almost useless since the two MG turrets have very poor turret traverse.

Usage in battles

Ammo choices:

Consider the following amuunition for battles: for the 75mm gun, bring ~20 shots of K.Gr.rot Pz. APCBC to deal with light and medium tanks, ~8 shots of Hl.Gr 38B HEAT for heavy tanks. For the 37mm gun, bring ~20 rounds of PzGr APHE for lightly armoured targets, and ~20 shots of  PzGr 40 APCR for medium and heavy targets. 

In general:

The Nb.Fz. is a tank much too big for its own good. The profile of the Nb.Fz. is very similar to the Soviet T-28. However, the armour of the Nb.Fz. is much too thin with the majority of the armour on the tank being 13 mm, even large sections of the front armour are this thickness. There certainly are lots of space inside between modules that there is a chance for a shell to pass through without causing significant damage. However, it is very easy for the enemy to target the main turret and knock out the necessary crew members to incapacitate the Nb.Fz.'s fighting ability, leading to follow-up movement for the enemy to close in to destroy the Nb.Fz.. As such, the Nb.Fz.'s imposing size is a paper tiger and should not imbue a player with the impression of a typical medium tank as even a 20 mm autocannon shell will easily tear apart the Nb.Fz.

Fire support:

The Nb.Fz.'s armour attribute relegates it to a support or ambush role that makes the most of the terrain for cover. Though the turret is mounted tall and is rather vulnerable to return fire, the tandem 75 mm and 37 mm gun on the same mantlet gives the Nb.Fz. several benefits when fighting from an emplaced position. Firstly, the gun elevation and depression angles are rather good so taking a position behind a hill to hide the hull while only exposing the turret is more feasible. Second, the manner the guns are mounted means that quick follow-up shots with little adjustments with the turret is possible, especially when changing optics with the weapon selection controls ("Select Primary Weapon" and "Select Secondary Weapon" in the controls). Thirdly, the fast reload speeds of about 3.5 seconds between the two guns means rapid firing rounds down a beaten zone is possible the Nb.Fz., possible denying an avenue of advance to the enemy if the Nb.Fz. can lockdown an area from its position. With a Hl.Gr 38B HEAT round available for the 75 mm, the Nb.Fz. can plink through even the fearsome B1 bis from the front.

Since the turret is located near the front of the hull, the Nb.Fz can comfortable peek out the front half only. By binding separate keys for firing the 75 mm and 37 mm guns, you can "one-two-punch" almost any tank you encounter such as Crusader, T-70, Chi-Ha, M3A1, etc. It is recommended to fire a similar type of ammunition across both guns to ensure unity in damage and penetration, for example use 37mm APHE and 75mm APCBC for lighter opponents, and 37mm APCR and 75mm HEAT against heavier tanks. When engaging enemies you can fire the 75mm first because it has better damage, then go after any still-conscious crew with the 37mm while the 75mm reloads. The Nb.Fz can fire quick salvos thanks to the fast reload of its cannons. 

Luckily the Nb.Fz has adequate speed to keep up with medium teammates allowing it to provide supporting fire in time. When moving, only do so to another cover that the Nb.Fz. can fight from. Do not expose the Nb.Fz. in the open as even heavy machine gun fire from a distance can penetrate the 13 mm armour plating on the sides, rear, and even the front at certain angles. Though the Nb.Fz. has the benefit of having a rather large volume of space inside for dead air, the engine takes a pretty large place in the tank that is easily destroyed from the side. If this immobilizes the Nb.Fz., it could spell a quick end pretty soon by follow-up enemy shots or incoming air attacks. Air attacks can also quickly destroy the Nb.Fz. if any planes with armaments larger than 12.7 mm come and strafe the Nb.Fz..

Unfortunately, most enemy tanks can knock out the Nb.Fz. with relative ease once it gets a shot in. Some significant worries the Nb.Fz. should be aware of are enemy heavy tanks and speedy vehicles carrying autocannons. Enemy heavy tanks like the B1 ter can be a big issue as none of the Nb.Fz.'s armaments, not even at close range, can reliably penetrate from the front (the B1 bis has slightly thinner armour that is easier to penetrate).

Avoid engaging in direct combat with the Nb.Fz.. Find a good terrain to cover the Nb.Fz. and use the tall turret and gun elevation angles to strike the enemy as they attempt to attack the point. Choose positions where you only need to deal with threats from one direction, as the Nb.Fz's slow turret rotation does not allow it to respond to targets around it fast enough which can be dangerous. For example, a straight street can be suitable, wheras an open field may not be.

Twin cannon tactic:

Its dual cannon design brings another interesting tactic: in a standoff between you and another enemy, both of you usually dare not to go out of cover and shoot first, and will just wait for the other side to shoot and miss. This type of situation can last for quite some minutes with conventional tanks, however you have the Nb.Fz. Turn your turret slightly so it is visible for the enemy, then deliberately fire the 37mm towards its general direction, and make sure to miss it or deliberatly bounce the shell. Seeing that you have fired and missed, most opponents will peek out and return fire thinking that you are still reloading. Now get your 75mm gun ready as the enemy tank appears from behind cover, and teach it a lesson with either a HEAT or APCBC depending on the opponent's model. This tactic will work even better if the Nb.Fz is covered with bushes to conceal its twin cannons. 

Enemies worth noting:

• B1: The HEAT shell for the 75 mm can generally be adequate against the B1 bis. If the B1 bis is angling, target its turret ring or copula to disable its 47mm gunner, make sure to use 75mm HEAT and 37mm APCR. Use the same ammo if you get to shoot the B1 bis's side or rear. Against a B1 ter, target the copula with APHE/APCBC so the shrapnel can travel downwards and knock out the 47mm gunner. Unfortunately the 75mm HEAT and 37mm APCR will be largely ineffective when shooting its hull side, so target its hull rear or turret sides and rear. 
• Valentine Mk I: the Valentine I is a bit easier to penetrate as its armour is 60mm compared to the B1's ~70mm, but it has a much stronger 40mm gun which you should avoid at all costs. Ammo from both of your cannons don't perform that much better against it, since experienced Valentine commanders will angle. Still you can target its turret front with HEAT/APCR. Knocking out the 2 crew inside its turret will destroy it as that's 2/3 of its crew. Concisely, as an early war tank, just avoid these heavy vehicles where possible and call for stronger teammates to help.
• SPAAG: Fast vehicles with autocannons, mostly self-propelled anti-aircraft guns, are also a concern as the autocannon can easily chew up the Nb.Fz. once they begin firing on it. Some examples are AS 42 and Flakpanzer 38. Although the Nb.Fz. has a typically faster turret traverse speed than the other contemporary German medium tanks, its not a big enough improvement to track a flanking vehicle should it catch the Nb.Fz. off guard.

Against the Nb.Fz:

• Light tanks & SPAAs: light vehicles like M2A4, A13, BT-5, etc should use their superior speed and maneuverbility to their advantage, and flank the Nb.Fz. The Nb.Fz has slow hull traverse, substandard turret rotation for all turrets, and sluggish acceleration, meaning it cannot deal with your surprise attack quickly and is certain to take damage. In a flank, destroy its driver or engine first so it cannot move, then wipe out its turret crew. No need to worry about it returning fire as its turret will never complete a 90° turn before you load your second shell/clip. However, if it happens to face you, shoot the right side of its main turret to knock out its gunner, then go for the rest of the crew. Never get hit by it though, as its cannons can fire explosive APHE/APHEBC or piercing APCR/HEAT which are all fatal for your light vehicle. 

Pros and cons

Pros:

• Can chain the two guns between reloads of each
• Both guns reload in similarly fast speeds
• High survivability due to numerous and well-spaced out crew
• More mobile than one would expect for such a large tank
• Good zoom on the guns

Cons:

• Armour is deceptively thin for such a large tank
• Top speed is nothing to write home about in this rank
• Would find its options limited when against the B1 bis, B1 ter, and Valentine I
• Awful turret traverse on all three turrets makes it hard to react well to multiple enemies, let alone flak trucks
• Large target

History

The Neubaufahrzeug was a prototype of what was to come with German heavy tanks. Historically, they were slow, heavy, and complicated. Not thought of as successful, only 5 were actually built. 3 of these tanks were sent to Norway at the start of the war, but only 1 of the 3 saw action. They were mostly used for propaganda.

In-game description

An experimental multi-turret medium tank. The first models were built in 1934. During construction the tank took on the designation of Neubaufahrzeug V (Nb.Fz.V) for the first two vehicles. The second series of three tanks had the designation Nb.Fz.VI.

In German military documentation the designation Panzerkampfwagen VII is also encountered; it was later replaced by Pz.Kpfw.IVnA (Panzerkampfwagen IV new Art). During the Norwegian campaign the tanks were also referred to in documents as Neubau-Pz.Kpfw.IV.

All three tanks of the second series were used during the Norwegian operation. They were officially part of the special tank battalion Panzer Abteilung zur besonderer Vervendung 40 (Pz.Abt1. Zb.V 40). The tanks were combined into one company under the command of Lt. Hans Horstmann.

The official name of this subdivision in battalion documentation was Zug "Plutos", but it was most commonly referred to by its commander's name as Panzerzug "Horstmann". The company's emblem was a mammoth's head located in front of the driver's cabin.
