Armour on the BA-11 is unfortunately inadequate against most tank armaments that it can encounter. It's only thick enough to resist rifle-calibre machine guns from coaxials, whereas heavy machine gun rounds have more than enough power to shred the car's body apart. In terms of surviving a front-on encounter with a tank shell, the only hope is that the engine and fuel tank modules will stop the shell from reaching the crew compartment. However, this hope is mired by the fact that the BA-11 has the hull-break mechanic enabled, so such a shot can ruin the BA-11. Even if the shot doesn't enact the hull-break mechanic, it will immobilize the BA-11 and leave it ready for a more accurate follow-up shot to finish the deed.

The only survivability enhancement the BA-11 can go through is simply to not get hit. Nearly every compartment of the BA-11 has critical components that would cripple the vehicle if not outright destroy it. The front compartment with engine and transmission module can hull-break or immobilise the vehicle. The center driving compartment containing the driver and another crew member, with the transmission right underneath to, again, cripple the vehicle's mobility or activate hull-break. The fighting compartment in the rear with the turret is fully stowed with ammunition with the gun crew, and so a shot there can cause an ammunition detonation that would make short work of the BA-11's life.

Finally, the roof armour on the BA-11 is not sufficient against most type of strafing attacks either, so enemy aircraft going for a gun run will be dangerous to a BA-11 user.

Notes:

  • Shells in racks 1 and 2 (turret) are modeled individually and disappear after having been shot or loaded.
  • Shells in racks 3 to 8 (flanks) are modeled by sets of 4 and disappear after all shells in the set having been loaded or shot.
  • Racks 3 to 8 deplete symmetrically by sets of 4 shells, starting with the left side.
  • Pack 21 (+93) shells (racks 1 to 7 emptied) to go into battle with the turret and the flanks empty of ammo.

The small caliber of the DT machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help. The clip capacity of the machine gun is quite poor, as it relies on a magazine of 63 bullets instead of a belt like similar machine guns from other nations.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Good gun depression of 8 degrees
  • Car forward mobility is quite good off and on-road, so long as it can pick up speed
  • Front profile rather small due to its long body

Cons:

  • Armour is only sufficient against rifle-calibre machine guns, anything more will shred the car apart
  • Roof armour above the crew at its thickest is 8 mm, which allows most aircraft to penetrate with a strafing run
  • Interior layout allows any penetrating shot to deal critical damage to something
  • Vehicle length means it can present a large target if driving perpendicular to an enemy's gun
  • Reverse speed is disappointing, restricting ability to withdraw into cover easily

History

Armoured cars were one of the most popular world trends in the development of armoured vehicles in the pre-war period. The Soviet heavy armoured vehicle BA-11 was one of the typical examples of this type of vehicle. It was created on the basis of a shortened chassis from the military ZIS-6 - a three-axle off-road truck designed on a scheme of 6x4 (rear wheel drive). The new chassis designed by engineers of the Moscow Automobile Plant was supposed to provide the armoured car greater payload and a better cross-country ability which allows improvements in the armour and a better off-road performance in the vehicle.

Compared to the armoured vehicles of the B-6 and B-10 series which had been designed on the basis of the GAZ-AAA truck, the armour of the BA-11 has been increased by 1.5-2 times and in some places, the BA-11 was slightly better armoured than the T-26 and BT-7 tanks. With the increased weight up to 8 tons, the vehicle maintained good driving characteristics: a speed of up to 64 km/h on the highway and 26 km/h over terrain. As well as in the BA-10 the designers also provided overall tracks which were able to help the armoured car to overcome particularly difficult areas. The gun and the turret of the vehicle also receives a 45 mm 20-K cannon from the BA-10 in the turret.

The heavy BA-11 armoured vehicle was produced in limited edition in 1939 and participated in battles at the early stages of WWII. In 1942 it was withdrawn from service.
