it doens't matter what they are holding, my friend was one of
the standby member for the raid, their order is simple, anyone that
move in the cabin, shoot first, ask later, i cannot disclose more
but it is the last thing in their mind if the terrorists are
holding knifes or guns, or bombs...
U must understand that in the world of special ops community, they
don't care who their opponents are, their role is very simple. Even
if it took 1 to kill 1, they would still do it without any
doubt.
It is the same for the SDU in HK in early days where they met
robbers from mainland china who has military background and armed
with AKs. They don't care.
