By shooting dummy
I was severely outgunned and hiding behind a bunker. Knowing that my time was short I lunged out and tried to take someone with me. At the exact time I went around the the right side of the bunker, someone else bunkered me from the left side and hit me three times in the small of the back. The big problem wasn't that I got hit but that he was shooting hot (well over 300fps) and so I was left with these beauties through two shirts. I still have some light scars years later while the major damage healed in about six weeks.
