Every other Support Weapon is a specialization, from heavy-fuckers, to medium-fuckers, to light-fuckers, to aerial-fuckers. RR/EATs/Quasar/Spear will fuck up ultraheavies and heavies in one-to-two hits, Laser Cannon/AMR/HMG/Commando/Railgun/WASP will fuck up mediums very quickly and do good (but not great) work on heavies, Airburst/MG/Stalwart/Flamethrower will fuck up lights, do impressive work on mediums, and technically "work" for some heavies.
The Autocannon will do a good job against all of these. Taking out Harvesters/Fleshmobs/Hulks/Factory Striders/War Striders can be done, but with some mild work.
Alpha Commanders/Warriors/Stalkers/Overseers/Devastators/Berserkers will all take significant damage from either its APHET rounds or its Flak.
Everything else can be swatted away with one or two rounds of Flak, and aerial units are insanely weak to its Flak.
It is the one weapon that does EVERYTHING "good enough", but nothing EXCEEDINGLY well that isn't outclassed by some other weapon with some exceptions to skill (such as severing a Harvesters legs with well-aimed shots on its joints, killing a Hulk in 2 shots to its visor, or bringing down a Factory Strider with a mag of APHET to its bay doors on its belly)
If it can't eliminate it outright, it will cause significant damage to it OR nullify some of that enemies advantages like softening armor on bugs, destroying subsystems like the turrets on FS's, or staggering enemies)
