Wow... i didn't know it is so complex :| You are right man, and worst of all is that tank moving at high speed would lay thinner smoke than one moving at low speed... and i supose there are many, many for problem to be solved for such unimportant thing, it's in oposition to "economy of force" during game making
But i think you should consider some kindes of smoke and dust to reduce range of TI and IR sights... i supose even some Air to Ground wepons would be unable to get lock on on targets. I know that this things are mayby hard to implant but... WinSPMBT is one o the best startegies i ever played and i hope it will be even better. Cheers man good work with the game.
