Half of the figures are in a very specifically VDV jump suit, so not really suitable. The other half are in a two piece camouflage uniform, which the Naval Infantry may have worn but most photos I have seen show either the black tunic and trousers or the one-piece KMLK camo suit.
The Under Fire minis are from the same sculptor as the Empress ones and come in steel helmets, which would be a far more likely head wear in combat.
