General info
Fitting as a variant of the M61 Vulcan, the M168 retains the weapon's notable high rate of fire for an anti-aircraft role. The high rate of fire of the weapon ensures that in the event of a hit, multiple rounds can potentially hit and either cripple or destroy the air asset.

Comparison with analogues
In the game, very few other anti-aircraft armament can match the fire rate of the M168 as the others consist of multiple single-barreled armaments on a vehicle mount rather than a rotary cannon design.
That said, one of the few weapons that is close to the M168's rate of fire and lethality is the 23 mm AZP-23 on the ZSU-23-4 SPAAG, which altogether with four cannons can reach a rather high rate of fire.
