General info
Survivability and armour
Armour is practically nonexistent with this vehicle at only 14 mm maximum. Notable weak spots are between the gunner and driver section, where the ammunition is stored. Four crew members are used with operating this vehicle, a driver, commander, loader, and gunner. It is typical for such a lightly armoured vehicle as this to stay behind in the spawn area, keeping an eye out for planes. Planes are usually an easy target to take down with your rapid firing 15 mm machine guns, so long as you don't use H-Pzgr, which will most often over-penetrate and cause less damage.
Armour type:
- Rolled homogeneous armour (hull, gun shield)
- Wheel (front tires)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 14.5 mm (20°) Engine compartment 14.5 mm (29°) Driver cabin 8 mm (30°) Roof panel 8 mm (41°) Lower glacis |
8 mm (41°) Top - Engine 8 mm (35°) Top - Crew compartment 8 mm (30°) Top - Roof panel 8 mm (19°) Bottom - Engine 8 mm (34°) Bottom - Crew compartment 8 mm + 8 mm (34°) Storage bins 8 mm Bottom - Undercarriage |

| Gun shield | 14.5 mm (33°) | 14.5 mm (13°) | N/A | |
Notes:
- Suspension wheels and tracks are 15 mm thick while torsion bars are 10 mm thick.
- Wheels are 10 mm thick and mudguards are 5 mm thick.
- The belly armour is 5.5 mm thick.

Usage in battles
Because of the lack of effective armour, it is highly recommended that you stay behind at spawn, keeping an eye out for aircraft. If you have the H-Pzgr modification researched, the option to engage some tanks presents itself. The H-Pzgr ammo belt can penetrate 64 mm of armour at 10 m, so flanking and shooting for lower side armour is possible. When you first unlock the vehicle it is a hopeless task to try and become an anti-tank SPAA, the default ammunition type is good for destroying light vehicles and planes. Once you research the H-Psgr ammunition belt you have the opportunity to become both anti-air and anti- tank. If anti-tank duties are chosen, beware of heavy tanks such as the KV-1. The minimum armour thickness you will face is 75 mm, so that puts completely destroying those heavy tanks out of the question. Avoid if at all possible, but if you can't avoid, aim for the cannon barrel and tracks to give you time to escape.
Pros and cons
Pros:
- Fast rate of fire
- Three machine guns can make accurate aiming less important because of the large volume of fire
- Has an dedicated anti tank belt, the H-Pzgr., which can go through most tanks from the side
- Good top speed
- Very fast turret traverse
- Crew members are quite spread out, difficult to one shot without HEAT
Cons:
- Armour is extremely poor, can be penetrated by heavy machine guns and can be easily destroyed by overpressure
- Open topped, strafing planes can be devastating
- Near non-existent gun depression
- Gun elevation is quite poor for an anti-air vehicle.
- Reload time stock of 18.2 seconds can be dangerous
- Acceleration is mediocre at best
- Heavy calibre machine guns lack stopping power compared to the previous 20 mm and 37 mm cannons
History
Devblog
By 1942, German engineers recognized the need of the Wehrmacht for a light SPAAG to provide cover for frontline troops against low flying aircraft and set about developing a suitable vehicle on the chassis of available halftrack designs. In 1943, this need became even more emphasized with limited German production capacities being unable to produce the required number of Flakpanzers that the Wehrmacht had been requesting.
Subsequently, German engineers decided to outfit the widely used Sd.Kfz. 251 halftrack with a three-barrel AA mount, initially equipped with 15 mm, later with 20 mm cannons, in order to meet the Wehrmacht's demand. The new modification became known as the Sd.Kfz 251/21 and went into production in 1944.
By the time the Sd.Kfz. 251/21 entered service, troops more widely used it as a support vehicle in the late stages of the war, with the vehicle performing well in this role. Nonetheless, over 380 units of the Sd.Kfz. 251/21 were produced until the end of the war, many of which through conversion of older modifications.
