Some of the vets here on FR say they'd love to get back into combat (SOME, not all).
As a former professional warrior, I consider it my responsibility to go into combat.
I am a warrior.
I am trained to complete my mission, because I have spent many years learning tactics, the operational arts, combined with the efficient use of firepower.
What you see here on FR is a recognition by former professionals who understand that it takes many years of practice, discipline, and money to trian professional soldiers who are able to subdue emotions for a greater good.
Elite Soliders are not "itchy" for combat - but they recognize that they are prepared emotionally, they are trained, and it falls to them to do the ugly job - and they do it.
That's the difference between young recruits just out of boot
The professional soldier, with nearly 15 years of training, will enter a building, engage the enemy, kill the enemy, complete the assignment and then self-extracate, if needed.
The young warrior is willing - but likely to make mistakes more often because of inexperience, unfamiliarity, and emotional reaction.
So, if someone has to go - the professional will volunteer to go because he doesn't want his buddies to be killed. He goes to protect them, and to complete the mission.
A great book to read on the wannabe culture is "Stolen Valor" by B.G. Burkett.
Don't get sucked in by the wannabe "combat vets" here on FR, and there are a lot more than just SOME....
I mostly see vets itching to just do something, anything to help. Feeling helpless sucks, especially after you've been trained and accustomed to be able to react to a crisis.
