MJ, bit of a flap one Taceval at ISL. Intruders had SLR with BFU, our ground crew just had SLR. When the enemy was captured they shared out the blanks and happily blazed away without BFU s.
As for not aiming at anyone, easy to say and harder to do in the heat of the moment. In fact you have to aim deliberately away from the target, you can't Fire indiscriminately.
