I have zero experience with modding, so I figured I'd put this idea out there in case anyone's interested in making it happen.

Basically, the idea is an equipment "item" that takes one slot, and allows you to move faster while equipped--maybe 20-25% faster. Think of it like the empty-handed sprinting you see in Arma 3, and you've got the idea. It'd be super useful for covering more distance in larger, more open maps, especially when no vehicles are handy.

I don't think there's anything like this in the workshop, at least not that I could find. If there is, please drop a link to it!
