Sim munition is well.... To put it in a way to understand, is like paintball, only with real guns... And fired like a real bullet, these can cause bleeding and rip through clothing.

As you may guess, they hurt a lot, but this is urban combat in an abandoned village, it was dark and I could only see the torched on the enemy guns, I emptied a full magazine into them, I didn't have a torch on, but they could see me, and my mask was clouding up so it was heard to see.

I had a jam, and only had to get down the steps to fix it, but I had to run down the corridor to the stairs, and the enemy were at the other side, I ran past a few of my mates, I wasn't worried about them shooting me, but the enemy team shot me right in my ass, I swear that hurt, but then our corporal shot me in the balls, right where the groin guard couldn't protect, I couldn't even stand up.

I later found out that the enemy had double tapped me, so I was shot in the ass twice, but I shot a few in the legs, groins and even hands, and trust me, it doesn't look pretty  as I have scabbes the size of penny,
