going back to the original question;
"Sort of".
I would've liked to see a clear separation between 'support weapons' and 'standard weapons', possibly something along the lines of a set of 'ammo boxes' for the support weapon column.
in this case, your 'support weapons' would be 'mech/vehicle scale weapons like the aforementioned SRM/LRM launchers, man-portable PPC units, support lasers and support MG's.
Every nth man killed in the platoon, you tick off a box.
Standards would have longer ranges against other light infantry units so that platoons don't have to be standing in each other's boots to inflict damage.
but then, I'd take the 'anti infantry' weapons and proably triple their range going from 'mech to man. (IOW a 'mech mounted MG would do 2d6-out to 18 hexes or so against unprotected infantry in the open.) far outranging the infantry's anti-'mech weapons (with the exception of field gun units, which would be specifically tied to mechanized type.)
Thus, keeping infantry 'relevant', but also preventing the "sword platoon with sniper rifles" from damaging 'mechs out to 6 hexes with 24 damage from the vibroswords somehow magically transporting their cutting edges 180 some-odd meters across open ground.
(and other hilarious misreadings of the rules).
also a separate 'box' for one-shot weapons like VLAWs and the like, which could give a platoon a 20-28 point hit...once in a battle scenario (unless they're adjacent to something like a j-27 ammo transport or an actual, separate, has-its-own-stats APC.)
Dug in infantry would get variable protections:
In woods: 1/2 damage (manpower losses, still tracking by deadguys) from anti-infantry weapons (except fire, fire kills everything.)
In Rubble: 1/4 damage
Hardened positions: 'mech weapons do 'mech damage. a Machine gun against hardened, prepared positions will kill one guy if it kills anyone at all, but an autocannon 5 will smear five guys into paste and reduce the structure to rubble on that facing/hex.
see what I'm saying?
