AFCAM should be about knowing you are under fire and continuing the mission. If you see someone wearing the AFCAM you know that person has stared down death and knows how that realization effects them, for better or worse. It basically says this person has been there and done that. Being on a base that gets mortared, NO. Being in a convoy that gets ambushed, YES. Flying into a DZ/LZ under fire, YES. Strafing a target while receiving return fire, YES. Defending against an IADS to include missile launches, YES. Shooting back against a no kidding ground threats, YES. Watching a MANPADS launch and reacting, YES. Being in a chow hall that receives a direct mortar hit and despite ringing ears and dizzy head, you help with caring for wounded, YES.
This should be one of those things, that if you aren't 100% sure you qualify, you should be ashamed of putting yourself in for.
