The commando's key weapon is the cannon, which gives higher armor than the rest of the classes, and it's not a slight difference either. But the cannons have low dps, but the aoe it provides brightens it up. Comms these days near cap uses a hard 6 and a shield, and preferably an implant. The cannon kinda sucks on dps and the aoe isn't too helpful, so comms are easily willing to sacrifice armor to increase the dps greatly. Comms are also good with napalms. The armor value provided when equipped isn't a lot, but the many advantages with the napalm makes it as none of a big deal. I've seen ops with napalms near cap with lame armor, and engies the armor is a bit better. But comms have the most armor value out of all classes, so a comm with a napalm is a delicious combination. In case if you need to know, ops have the highest dps out of all other classes, and engies have healing abilities none like other classes. But in case if you get a napalm, you will encounter ops with more armor, because the dual pistols provide the armor. So the napalm won't do much help in pvp, so I think a pistol/shield/implant will be a better idea, or maybe a cannon itself. Sorry to put some useless remarks out there. But it might come to help, so... ya.
