General info
Survivability and armour
Armour is not on the operator's side in the M163, as it is thin enough to be destroyed by 12.7 mm machine guns from the sides and rear, and any cannon-sized armament from the front. The turret is partially open, leaving the crew vulnerable to enemy light arms fire. If attacked, the best bet for taking a hit and surviving is to point the engine towards the enemy and hope it absorbs the shot.

Armaments
Main armament
The M163 is equipped with a 20 mm M168 VADS, or Vulcan air defence system. The M168 is a variant of the M61 cannon, which can be found in-game on vehicles such as the Japanese T-2, and the American F-4C Phantom II. Used initially during the Vietnam war, the M168 was a 20 mm air-cooled rotary cannon attached to a small turret on the M163. Dangerous to anything in the sky, it will lock on and rip through anything in its path.

Usage in battles
The M163 has an amazing rate of fire with the M168 gun, thus it has amazing damage output. In an anti-aircraft role, it is best used as a point-defence SPAA, defending a group of allies/cap zone from air attack. Its range isn't as good as the M247, so it's best to keep in mind the approximate 1 km targeting zone of the M163.
The M163 wields about 60 mm of penetration, which is enough to mortally wound/destroy many Axis-country's vehicles such as the Leopard, AUBL, and Centauro.
The high rate of fire also allows the M163 a sort of CIWS (Close-In Weapon System) type of role, as it can easily spray in the direction of an incoming bomb, thus destroying it and saving nearby allies. This is especially easy against the infamous FAB-5000 bomb from the Russian Pe-8, as the bomb is large and easy to track.
Radars
The M163 is equipped with an AN/VPS-2 tracking radar, with no search radar. The radar is fitted to the side of the turret.

In order to lock on you must be looking through your sight, position the crosshair over a target (within 7 km) and press the lock on key. The target must be within a 2° cone from the centre of the crosshair. |

Pros and cons
Pros:
- Amphibious
- Quick acceleration
- Good traverse, especially when fully upgraded
- Insane rate of fire of 3,000 rpm; can literally shred incoming enemy aircraft, AP rounds are dangerous against lightly armoured vehicles
- Has a tracking radar
Cons:
- Light armour
- Top speed of 32 km/h off-road when stock
- Not keen to climbing hills until performance modules are equipped
- Relatively slow for the rank
- Slow in water
- Inaccurate/wobbly in water
- One of the longest rearm/reload times in the game
- No search radar
- Effective range is not good for a rank V SPAA
- Inaccurate while approaching far targets
History
The M163 VADS was a self-propelled anti-aircraft gun (SPAAG) based on the chassis of the M113 armored personnel carrier (APC). It was nearly unmodified from the base M113, and featured the same armor scheme, rear loading ramp, and the General Motors 6V53 series 6-cylinder 2-cycle diesel engine (212 hp). An open-topped turret was fitted to the center of the roof of the vehicle, and an M61 Vulcan 20mm rotary cannon was mounted in the turret. The gun could fire at 3,000 rpm or 1,000 rpm, and the elevation was from -5° to +80°. The M163 was operated by a crew of four, and there was a wide variety of ammunition for the main gun. A tracking radar was fitted to the turret to improve the chances of destroying an enemy aircraft.
