I use to be a member of a very select group, my team were the people that were called when the talking was over, and it was time for people to die.
Getting on this team isn't very easy and I have been through some very intense physical, emotional, and mental testing. One of the final tests has raised a question in me about morality...
Has anyone ever heard of 'Sim-unitions'? To make a long story short they are a real bullet with the lead and powder removed, a rubber paint ball type cap is what the lead is replaced by and the firing cap(primer) is what propelles the 'bullet' (at a much reduced velocity). Needless to say they are less than lethal but much worse than regular commercial paintball. Being shot by one of the projectiles is akin to getting kicked by a mule. A chest hit will knock the wind out of you, a shot in the arm makes the arm useless for quite a while. If you ever got shot by one you would definately know it and would not be able to pretend that you weren't. They were developed for training exercises because they allow the use of your usual firearm while being less than lethal.
After 'making the team' I was activated within 24 hours of acceptence. I got to our meeting point and some of the earlier arrivals were already loading equiptment into our vehicles. I asked the first person I got to what was going on and was promptly told to "Shut Up", get your stuff and get dialed in. I got into our vehicle and asked one of the other newbies what was going on, "a drill?" I said. His response was to show me weapons with 'live' ammo (we don't take live ammo on drills).
