35mm autocannon

The 35mm autocannon is a Jiralhanae weapon mounted on the Type-25 Chopper, which originally used Type-25 Spikers mounted on the sides when the vehicle was first designed.

Description
The 35mm autocannons are the primary offensive asset of Jiralhanae Type-25 Choppers, and each Chopper is mounted with four linked forward-firing 35mm autocannons. This cannon is surprisingly powerful, and its ammunition is probably a smaller form of the Type-25 Brute Shot round, fired at a slower rate.

The term "autocannon" is not entirely accurate when referring to the weapon due to its alien design. However, it is self-loading and fires explosive projectiles larger than 20mm much like its human-made counterparts.

Tactics

 * The 35mm autocannon uses a very powerful shell, but has a very low rate of fire.
 * The rounds are too slow to take down fast targets, and so it is most effective to lead targets.
 * Use this gun on short-medium range.
 * Drive forward or stop momentarily, because the guns are forward mounted on a mobile section of the Chopper.
 * Don not attempt to use this gun against multiple targets simultaneously.
 * Repeatedly tap the fire button instead of holding it down. This will increase the rate of fire.
 * When facing this weapon, effective countering tactics are to:
 * Avoid the incoming rounds, which are slow enough
 * Prepare an anti vehicle weapon, as the driver may attempt to splatter you.
 * Try to attack a Chopper driver with one or more allies: he/she won't be able to lead and shoot down multiple targets surrounding his/her craft
 * The 35mm autocannon can only shoot down one enemy at a time, so don't rush among enemy formations, and don't stay there for too long, for this greatly increases the chances of you being killed.
 * Avoid excessive turning while firing as this will throw off the rounds' trajectory.
 * Do not use it against aircraft.
 * The autocannons do produce some kickback, so when you are trying to pull off some move that requires lots of mobility you are advised to stop firing.
