Had a fun idea based on Elementals carried on Mechs. Essentially, if a Mech gets hit in a location that carries Battlearmor, the Battlearmor takes damage first.
So, Smart Armor:
Little more than a semi-mobile robotic slab of metal with an attachment grip, this battlearmor is made for the sole purpose of climbing on to a Mech and remaining in place, taking hits that would normally damage the larger Mech. Far more expensive per ton than the equivalent protection in basic armor, these smart robotic armor units can be attached to any unit that needs a bit more protection than normal. They are commonly used on the lighter Veemechs as those frames have less armor to begin with.
Examples:
Light Smart Armor:
4 'suits', 6 pts armor each, movement 1/1/3, Battle claw on one arm and basic Manipulator on other, 260 kg cargo on each, 1.7 million C-Bs per squad, 27 BV/suit, or 425k C-B per suit (~71k/pt of armor)
Medium Smart Armor:
4 'suits', 10 pts armor each, movement 1/1/3, Battle claw on one arm and basic Manipulator on other, 160 kg cargo on each, 2.36 million C-Bs per squad, 44 BV/suit, or 590k C-B per suit (59k/pt of armor)
Heavy Smart armor:
4 'suits', 16 pts armor each, movement 1/1/2, Battle claw on one arm and basic Manipulator on other, 235 kg cargo on each, 3.22 million C-Bs per squad, 56.25 BV/suit, or 805k C-B per suit (50.4k/pt of armor)
Jump had to be strong enough that the suit could 'hop into position onto the Veemech to be protected, speed didn't need to be that high, and the Battle Claw was selected so the Smart Armor could grab on to a Mech. Basic manipulator was selected so these Smart Armors could help out with tasks around a base where wanted.
As a comparison, 1 ton of armor on a 100-ton Mech will provide 16 pts of protection, at a cost of 20k C-Bills.
The fun part is these can be extended to semi-mobile cargo pods, using an unarmored Light BA as an example you have a 365k C-Bill cargo pod that can carry 560 kg of cargo in an unarmored pod. Not as efficient as a true cargo carrier, but it allows the controller to stop in the hex for one turn, command all the little cargo pods to Jump aboard, and (hopefully) get out of trouble. Much faster than standard cargo loading rates.
