I got lucky that in my deployment I only drew my weapon three times. Once at a kid who scared the f**k outta me, once at a hyena running right at me, and then on a truck I thought was rigged to explode.
All turned out ok. The truck was squatting down on its back axle but it was just a load of dirt instead of explosives. The occupants were scared shitless and thought we were about to kill them.
But I was merely talking about through the two jobs I had in the Army, I got to work with a weapon system capable of removing entire grid squares off the map in the Himars, and later became a combat engineer in a sapper unit. Sappers are usually the crazies that run around with the infantry and blow up enemy controlled bridges, blow holes in makeshift airfields to keep enemy birds from landing in them, and blow holes in their obstacles to allow the infantry through.
I'm glad I wasn't actually in combat though, because against a true near tier enemy combat engineers have a horrific casualty rate.
