Best load out for the little bird?

Miniguns if you are good with them. You can damage heavy armour but its better for choppers. Heat seekers for air vehicles. I like air radar so you don’t get snuck up on and flares or ecm jammers are good

Might now be the best, but always run 25mm main, and switch between laser guided and heatseekers. For countermeasures I use ecm jammer

Whats does ecm jammer exactly do?

Blocks lock on missiles
