All you need is a object they fcked up, some free time, order to do some military exercises from Army HQ and a digicam.
For some reason CRS "overmodelled" the reloading time of 20mm FlaK30 AA-cannon by over 100% while "other side" has it's cannons reload times modelled very accurate.
Even when a guy who served in the army in the AA regiment and knows his stuff said it was fubared CRS didn't even bother to reply.
You guys have it pretty good here and personally I'm waiting what AH-II brings to the game genre

Oh and film I was talking about can be found from
