Kama on BF2 units

[Giftheck]

Could somebody model the ARC kama onto the BF2 Heavy Trooper and Sniper, and also the Ep3 Commander model I use in my Main Play Mod assets, and the Snowtrooper kama onto the BF2 Clone Commander? Hex-editing them on doesn't seem to be working - they look fine in MSH viewer but act odd in-game.
