Yea, I've done a lot of shooting over the past 35 years. I'm familiar with recoil impacts, range, ballistics and all that other stuff. My guy carries an M1A which is 7.62mm (.308).

[@Section] I hope you don't mind me bringing along a couple NPCs. They are "Joe's" adult children ages 22 and 21. Although Joe Sr. is not going to operate inside the T72, Joe Jr might. But if I am not mistaken, the T72 has an auto loader, so no human is required for that. Besides the TC (Tank Commander) all you have left is the Driver and Gunner. You want these two to be NPCs. It would be so much easier for you that way. My characters, can dismount and serve as scouts when needed. My main character is loosely based on me. I had to cut his military career short because something killed everyone in 2016. But up until then it is close.
