The 30mm Cannon is a default vehicle weapon in Battlefield 3 available only for the Russian ground Force's Su-35BM Flanker E, Mi-28 Havoc and Pantsir-S1. The weapon's faction-based counter-parts are the U.S Marine Corps' 20mm M61A1 Vulcan mounted aboard the F/A-18E Super-Hornet, Centurion C-RAM and the M197 Gatling Cannon aboard the AH-1Z Viper. Although different in calibre, both cannons deal the same amount of damage and are only different in aesthetic appearances.
