it depends on the situation. usually at training commands such as boot camp we were instructed to carry condition 3(no round chambered and safety on). however in an actual FPCON environment it tended to be round chambered safety on(what they referred to as condition 1 though definitions seem to vary between civilian and military apparently)
if it's some kid that's never held a gun in their life you bet they are going to have you carry with nothing down the pipe but if you've got a suicide bomber racing towards an ECP what condition do you think the troops defending it are going to be in that offers the fastest response?
