I cannot blame the system.
Imagine you are an ordinary postal worker and have no clue about inert or live ammo.
You accidentaly drop a package and a 50mm inert AA shell rolls out.
Freaking out is understandable, especially these days when terrorists are really active.
Although I understand it sux since it will be very hard to get, lets say, a fake ammo belt for your STAR M249
Heh, also I can say goodbye to my plans of getting a ww2 repro german grenade :banghead:
