2 x 40mm rounds into an open field? That's it? No fucking way......
Couple of years ago an SF team engaged a dude who was talking on a cell phone and pointing at the SF unit. The local then picked up an RPG before catching a .300 Win Mag to the chest. They didn't play "mother may I" with the TOC before pulling the trigger; their BN CDR threatened a 15-6.
When I hear about an SF unit with no support, I don't bat an eye because it is sadly too common.
