When they sent my kid off to Kuwait in 2002, they told him he would carry only a 9mm pistol into battle because, as the tank driver, he didn't have room for a rifle.
So, I sent him two 30-round magazines for it. He received them only two days before 3/7 Cavalry led the charge into Iraq. The quartermaster gave him an extra hundred rounds of ammo to load the magazines.
First battle, a guy came charging toward him. As he told me when he got home, "I shot him dead center-of-mass with my Beretta, and it just pissed him off!"
So, naturally, I asked, "What did you do?"
"Well, I had one of those 30-round mags in the weapon, so I shot the mother***er 29 more times. Calmed him right down."
