Always go off, and no doubt as to who was hit
I'm a firm believer in using grenades during scenario games. They can rapidly clear areas and allow your team to push forward and take over objectives fast. I personally throw at least 3 cases of grenades per scenario game, and it's not unusual to see me with 2 cases hanging off of me during the final battle. Why would I waste all of that money if these things didn't work? I've had Tippmanns and no-names thrown back at me, that is never a problem with Atomics. The fill marks decisively, there will be no arguments on whether you hit someone or not. The manufacturer listens to his customers, and has greatly improved on the product over this past year. The fill is 100% stable and now comes slightly scented.
There's a reason why the best scenario teams in the country use Atomic Ordnance Grenades. They work everytime, all the time. I've tried the rest and I'll stick with the best. Atomic Big Boys!
