lmao I almost never see people use the stuH, and when I do I sometimes ask people how many kills they get and its usually none or a couple. It's too hard to use it as a CS tank and cut spawns/buildings/bunkers when you fire 1 round every 15-20 seconds. Plus its hard to use it most situations. For example, if there is an ei in front of you behind a berm, you have to contact that EI with the round, which is a very very precise shot. If you hit the berm in front of the ei, it won't damage the ei. then you have to wait 15-20 seconds for a reload. With a mg, you can hold down your fire button while you make a slight adjustment to your aim. Next is cutting things. So say they have a depot on one side of a street and the CP for the depot on the other side. you are trying to cut. You have to either contact the ei with the round or place it super close to him. That depth perception is very hard to calculate in the limited time you have to fire while an ei is sprinting across the road. Even if you are a great shot, itll still take 15-20 seconds to reload, which means more and more ei crossing that road. Plus, if EI smoke the road, you are screwed. you have 1 shot every 15-20 seconds to have an attempt to get ultra lucky and hit an ei crossing, where if you had a MG, you could just lay down a continuous stream of fire or bursts into the smoke.
I think I made my point here and I hope this makes sense as to why people don't use it.
My statement isn't to argue if its historically accurate or not, it's to explain why people don't use it.
