South Korean OOB issue
 

I don't know if this has already been addressed behind the scenes, but the South Korean OOB uses weapon 053 "7.62 M240 AAMG" on almost every modern vehicle including M48A5K (units 017, 018, and 020) and K1/A1 tanks (021, 022, and 024). I've never seen a picture of any Korean vehicle with a mounted M240, and even if its planned or a recent upgrade, the fact is that these vehicles definity used the M60D AAMG and M60E2 co-ax at least until 2000. I don't know if a lack of stats difference was the reason for this choice, but I just wanted to point it out.
