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.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against the main opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.

Media
