That mental level of teamwork Robbo first alluded to is almost impossible to quantify.
I've often played alongside my brothers, people have commented at times that we have an almost uncanny understanding of each other and so little communication is required between us, more often than not I'll be saying single words like "go" just "knowing" which bunker they want to get to even though it may not always be the most obvious. Occasionally they've just got up and run past me, as have I, knowing that we'll see and adjust to get whatever job done is required.
Dynasty have "it" through years of playing together, Yosh, Ollie, Ryan and Alex have been playing together since their early teens and they practically live in each others shoes.
The Russians haven't been playing together as long as a unit but they also have "it" through the strictest training regime ever put together in paintball. Those guys are full time paintballers in that they train it, they play it, they learn it in an academic sense and train for almost all conceivable scenarios 3v2 for and against 2v1 for and against 3v3, 4v2, 5v2 etc etc. Their coaching crew have been known to figure out which bunkers to BOUNCE paintballs off in order to hit the other team (mentioned by one of the Ironmen in the days when Xball fields had "pin" bunkers). This is knowledge and training though, not necessarily the natural occasionally mythical bond which Dynasty demonstrated especially in the days of 7 man when they reigned supreme.
