I specifically said I read the rules and none of you answered my question. One of you even supported the part about tagginn rounds being left at the base for rearm but being able to reuse its shell but I was asking for a yes or no on "is there a way to keep track of how many times I have fired a bb swarm". If not is fine.
Also according to the rules, even a bb swarm is recognized as a way to take down vehicles as of this broken homes rules.
As for the tips on nerf, thank you, I will keep it in mind but it's looking like investing money into any of it is out of my league for now.
When the swarm shell is fired, it's fired. That's how you know. I'm not sure what more you're asking with that. If you carry 12, and fire each one once you've reached your compliment and have to rearm at a FOB or MRP. But when it comes down to it, this is a game of honor and integrity. It's hard for AMS to police every little thing in the field and trust is placed in players to play by the rules.
In reference to vehicles, I say this as someone who is a part of the cab crew for a technical at these events. When we know we've been hit with a rocket, or other rounds which would take us down, we absolutely call it. With a swarm type of round, we'd need to definitely be able to see it and know that's exactly what we were hit with. Just the sound isn't going to tell us anything because rolling into a firefight and being in the cab it sounds like someone is shaking a can full of rocks with all the noise from BB's bouncing off the body of the truck.
If you hit a vehicle with a swarm grenade and they don't call a hit, it's not that they are trying to cheat, they probably didn't see you firing it, and can't tell the difference between that and the barrage of rifle fire hitting the vehicle.
