A contradiction in Traveller? Surely not :CoW: :devil:
Frank Chadwick and Dave Nilsen contradicted just about all previous Traveller technology canon in TNE
More seriously, change one word in the LBB:4 entry for combat armour and we get:
Note that in LBB:1 vac suits have a mass that counts against character carrying capacity, while heavier and more bulky combat armour does not. This suggest there must be some sort of aid to dealing with its mass and bulk.
As to how it is powered, if it is electrically powered artificial muscle then TL11 battery and energy conversion technology probably obviate the need to track energy usage.
By the way does anyone know what is the battery life of a suit of battledress is?
