The answer is of course you can if it is means dislodging the OPFOR but you cannot take them out. You still need to do an actual airsoft gun hit, "knife kill", or BB/Pyro grenade blast to do that. It also depends on your gamesite treats such use. Bravo Whiskey plays in the snow with an MP5 in this gameplay video... "Hello airsoft world and all who inhabit it. Todays video is gameplay from my local field, The Bingfield, located in Alton, IL. As you can see we received a bit of snow that weekend which made for an absolute great day of pew pew. In addition of the snow, snowball hits were accounted for. So this made the day even better and more fun. I had a lot of fun this day and we had a great group of players out there. Hopefully you enjoy the video!"
