Quite a few canon DropShips or Warships (especially post-3050 designs) are specifically noted as equipping their onboard Marine complement with BattleArmor. And there's some interesting equipment available to Battle Armor that could help in that role. The Space variant of the Elemental is particularly well-equipped for such missions, and is probably what the Clans use for that role. We know that Inner Sphere bean counters will probably hand Great House navies standard suits (like the Inner Sphere Standard) and call it a day, but what if money was no object? What if you were to design a Battle Armor suit specifically for the conditions that would be likely to found inside a DropShip or Warship's corridors, and the dangers that could be found there (hull breaches sucking you out into space or simply venting the atmosphere on the deck you're fighting in, enemy Battle Armor boarding parties, tight quarters leaving a lot of weapons impractical/dangerous), what would it look like?
The rules of the challenge are as follows:
Tech base is entirely Inner Sphere. The Space Elemental makes any Clan submissions redundant.
This suit is intended for shipboard duties only. The only BattleMech-scale weaponry it should be encountering are those that can be fitted to enemy Battle Armor.
It should be given equipment that would either be useful for working/fighting on a ship, or aid in recovery from the previously mentioned disasters.
