I tried to place one like a frag tonight on the trip wire. It didn't allow me to hook it to the wire, sticks on the ground. Wanted me to unpin it.
Also would be nice to add smoke to this list.
It could alert someone if they are defending an area. Such as their complexes in the future.
grenade needs to be unpinned in order to attach it to a trip wire. u need to do so within 5 seconds after unpinning otherwise it will explode in your hands. attaching it will stop the timer.
when somebody walks through the trip wire it will also take 5 seconds for the grenade to explode
