I usually carry a couple taggin R2B grenades, but don't always use them. I also really only play a couple milsim games a year, so can't speak towards regular weekend games. I like them for dropping/tossing out of windows, or out of a wood line towards unsuspecting players, or if you're trapped in a room with the other team coming in, just drop it at your feet when the bust in and take them all with you.
