Right now there's simply not enough weapons for everyone, so in MP missions we mosty have to use same weapons for diffrerent factions, which isn't a good option.
All factions should have their own LMGs/MMGs for the infantry. Meaning, the following is still missing:
- 6.5 LMG for CSAT (RPK-74 kinda like chambered with 6.5 maybe?). Alternatively, Mk200 could be used for this;
- one or two 5.56 LMGs for AAF/FIA (FN Minimi/M249 SAW or maybe HK MG36/MG4);
- one or two 7.62 MMGs for NATO and AAF (FN Mag/M240/Rheinmetall MG3).
Ideally, all infantry should be able to interchange their mags with LMGs (like NATO is able to use 30rnd mags in MX SW right now), but that's a secondary problem.
