Well, i think that unit simply misses in the capitol armory.
Its a classic, and capitol misses a mid size thing..
i don´t want the huge MHMG or 3 W thing, but a medium guy with a twist..
something in the line of a space marine, not even a terminator in strengh
something like the Carnal Harvester, in strengh
CC RC PW LD AC WD ST MV AR SZ Cost
7 8 5 10 3 2 7 3 20 3 37P
Necrobiotic, Feast; Valcheck Light Machine Gun
Valcheck Light Machine Gun (Ballistic) CC: -3, PB: 2(x3), SR: 2(x2), MR: -1, DM: 11
the idea is simple: a 2 W model with a light machine gun and good armor.
i change from the CH: -1 Dam, -2 PW, -Feast
i add to X: +2 RC +2 LD +3 AR.
also, i want a twist: the armor supports the guns -> move & fire (no +3 RC if not moving).
i think that +3 cost & impenatrability justifies this ability at MV3!.
the only question: does MV3 limits the use of move&fire too much -> make the unit more expresive and add +1MV?

if you compare that to a attila:
CC RC PW LD AC WD ST MV AR SZ Cost
9 11 3 12 3 3 10 3 22 3 43
AI, Resolve: 3, Level 3 AI, Radiant attacks do +1 DM; CAV-4000 Autocannon
CAV-4000 Autocannon (Ballistic, Concussive) CC: -5, PB: 0, SR: -1, MR: -3, DM: 10(x2), AV: 2
the AC is +/- like the LMG, other stats are similar. Attila has resolve3, +1 LP (!), no impenatrability, no move & fire..
i think it equals out ~
since the rubic is not existent anymore, i propose squad size 2-6 40 P apice, elite
they would fill the role of guns-blasing-burst-into-the-critical-spot and could react to a thread (moving up to 9´and still get a shot or two)
after the initial engagement move & fire looses efficieny, therefore don´t makes the unit expremely good. other units with fly 5 are similar shooty/movelike
if they lead a charge they will of course be terrible effective (move&shot->lots of shots),
but 4 cost 160 P, that is also 4 Vulcans with dam 13mhmg but no move & shoot..
in the end, a new option with the movement and a hole in the capitol line of troops (a lot of rifles (&squad support), but nothing else (exept support/vehicle))
