I found out that javelins miss when you move your vehicles around at high speeds. So that would be my guide to operating them - don't park them around one spot and have deliberate and fast transitions between covers.
Damn, I don't even know where there are line 23-2s left other than the airborne and marines. I guess specialist AD units, but CM doesn't really portray them.
I'm not exactly sure how Kornets are so easily detectable in game. The coordinate-net laser for guidance net is magnitudes weaker than target laser used on classical reference systems.
You can't really carry more than two RPOs per person, so only four per squad. There should be 8 or so additional RPOs in the RPO Platoon MTLBs. That seems a bit low since the standard allocation for BMO-based platoons is 180 launchers, but I don't have the sources for MTLB to compare.
