I'd say most things have been said a hundred times before but here we are
Personally it seems to me to be totally unrealistic to see so many humvees and vodniks on the frontline - they're not combat vehicles, they're reconaissance and support trucks - and it bothers me ever so slightly that it seems normal to people here

APCs (without ATGMs) should be everywhere and the fast mode of transport of choice - LAV25s for the USMC, BTR90s for MEC, BTR70s for the insurgents etc. with IFVs like the Bradley, BMP3 etc doing the job that APCs are doing now. Just a thought...
Another thought would be to remove the overall one commander position and give all squadleaders access to the commander suite. That way Squadleaders can
- set waypoints and instructions on a map
- view their squad info immediately
- communicate with other squadleaders for coordination with the 'b' key and sending requests on the mapscreen
- if a single individual wishes to command they just have to lock a squad and use the commander suite as normal
