The top one is force trim, to lock the controls so u can get out, the middle one is to raise the rescue hoist or drop your cargo ( depending on the configuration) the hoist had a 22 cal long bullet to cut the cable in an emergency. this is like the one I flew a UH1 V which had the hoist and radar altimeter (which saved my bacon a few times) the pull trigger you can’t see on the front (missing) is half in intercom full pull radio, the bottom button is missile fire it is against the the Geneva Convention to have on a medevac bird with the large red crosses and missiles at the same time on both. I’m not the only one who has seen it done.
