Since you are using CSC: Any special options for BD/CA in there that even those fields down again?
Not sure about Central Supply Catalogue, but if we're moving beyond the main rulebook, Mercenary has a few useful bits of kit for the Mobile Infantry Wannabee (IFF HUD and Gyro-stabilizer Rig) and you're always able to up the ante to Artillery Battle Dress. Armour 20 and a twin Shuriken Ca....sorry, Mag-Rail Minigun....makes for something a lot scarier than conventional BD. Especially if you start adding in subdermal armour and/or the augmetics in the new Signs & Portents, like the IMA Grunt Exoskeleton or Frontier Armoured Skin replacement.
No, battle dress isn't the death of worlds and the drinker of suns. But it is quite nice. Sadly, it is a lot more than 'quite' expensive.
Is it worth the cost? In the abstract of equipping a mercenary regiment, no. Give 'em poly carapace and the god-given sense to use cover and you'll do fine. In the specific and much less cost-sensitive sense of me being the PC inside it and being shot at? Hell yes.
Is it overpriced? Probably. Not so much that it is an unrealistic price, but that the strength bonus is only really ever relevant when toting heavy weapons that PCs should be even less likely to have than the Battle Dress, and the benefit of the armour plate being made 'weightless' doesnt really affect the rules - but I can assure you that being after forced to tab a few miles in combat armour you'd damn well know about it.
Vaguely on topic:
Can you get Battle Dress as a Mustering Out gift in the core rules? No.
Would it be devastatingly broken if you could? No, it just doesn't seem like the sort of thing you're likely to be allowed out of the door with, in the same way you might be allowed to keep your service sidearm but not the heavy machine gun you spent your career manning.
Is it possible to get Battle Dress for a new PC? Yes. The last six pages of waffle represent people's opinions. If there is a disagreement between the GM's opinion and the rulebook, on any subject, then as far as that game is concerned the rulebook is wrong, end of.
