The larger paintball games use UAV's and they work fine, and nobody acts the bollox.
They are actually going to Sennybridge for a rather big game this summer, brother in law is a serious paintball milsimer.
They attach little GPS devices in their vests, and the UAVs pick up the signals and relay it back to command. I'm not sure on the actual "livefeed" in terms of time delay, but commanders have a relatively solid idea where their teams are.
They also use small blocksthat have little GPS transmitters, that they place in buildings or locations to mark enemy targets or structures for commanders to organise air strikes.
He was showing me a video on his phone of the command tent at the last event he was at.
For all the guff people give paintballers, the milsim paintballers are MILES head of airsoft when it comes to this stuff.
**** they even have transport with mounted 50cal cases, that have gravity fed markers inside them so it looks like a 50cal paintball marker.
We were seriously looking into the HUD setup for airsoft. It involved us having GPS transponders on our person, which relays your positions back to your commanders HUD, which literally was on his helmet and on a PDA.
Each team member also had a PDA system where they could mark targets which would be highlighted along with marking downed men, objectives etc etc
However the cost was significant, and required a method of data transfer between team members
But mostly because of the fact most games here are skirmishes and unorganised, the investment in a piece of tech that promotes organised gameplay would be a waste.
They are pretty much the norm in the US airsoft milsim scene afaik, forget the name, but it was a pricey setup at around the €300-400 mark.
