What training did you get? And did they inform you that you are to not let your guard down, do a sweep, the flanking team does a sweep, and then you set up security and the aid and litter team goes through the casualties and help those who are wounded and still alive? They taught me that. And did you serve? I only ask because I don't count training if it wasn't done while you were active and you were trained by an actual non commissioned officer certified to train you in tactics.
I went to basic January 27 2003. I caught the last 6 months of the invasion and went back July of 2005. Then back again in 2009. Then Afghanistan in 2010.
If you were trained to shoot people after you you pass the "threshold" then you were trained wrong and that leader set you up to go to prison. Now, what used to confuse me is the difference between a double tap and a controlled pair.
Controlled pair= shoot once, and then shoot again to put two in a baddy. That is when you are actually fighting and you have not "cleared" the area after contact. An example of this is if I jumped out at you shooting and you shoot me once in the chest and then quickly pull the trigger again to put me down. We do this because 5.56 rounds have little stopping power and you usually need two shots to put someone down and stop them from attacking.
Double Tap= the fighting has ended and you are now going through the bodies, looking for survivors, intel and basically making sure all is clear and you find one guy breathing and you shoot him to kill him. Example: My team is shooti8ng at the bad guys. Team B flanks, we shift fire and team B goes across the area killing any bad guys. Then we go through and do the same to whoever they missed. Then when all that is down we go back and check bodies and find a guy still alive. He is no longer shooting at us but we shoot him anyway. <---That will get you sent to prison.
I don't mean to be harsh, but if you served and an actual soldier in a leadership role taught you that, he needs to be removed from service because he will get people sent to prison for murder.
