I was doing a lot of work in the peripheral materials about the Earth Union’s powered armor technology and thought I’d share some of that with you. As most of you know, powered exoskeletons have been in development for a while and we may well see field deployment in the next ten or twenty years. There are of course a number of issues to consider, but we’re not going to go too far in depth with that.
By the start of the Earth Union, the original LightSuit S saw limited deployment among heavy weapons operators, combat engineers, construction engineers and materiel transporters. For those of you who have seen Edge of Tomorrow, imagine the Jacket technology scaled down a bit and with a little more armor. Things like mobility and battery life were the primary concerns which kept them from being general issue for combat arms. Subsequent versions improved on the design with modest gains, but the version of the LightSuit without the exoskeletal frame became the standard even though that was not the original plan.
The name LightSuit came from the fact that it was a much lighter and less bulky design than competitors, but there were always plans for larger scale units, but this did not gain much traction (or funding) until the government saw a spike in research funding in the 80s. This research would prove fortuitous because a number of the projects that went into development would prove invaluable in the arms race that kicked off with the start of the Sheol War.
The MediSuit was designed to be self-contained and deployable in all environments. The Mark 15 Heavy Duty EVA Suit developed in the wake of the Lunar Revolt represented the basic template, only the MediSuit was designed specifically for combat roles. One of the first assignments of a young Donovan Graves (future Commandant of the Marine Corps and Hero of the Union) was to serve as a test operator for the MediSuit prototype. The successes of the Mark 0 prototype let to the development of the Mark 1 production model, which began service in April of 100, less than a year after the official declaration of war by the Sheol Empire. The first MEU to fully integrate Mobile Armor saw action the following year with then-Colonel Graves as its commander.
As with the LightSuit before it, the MediSuit’s design went back and forth between the competing goals of strength and mobility. Low-gravity environments made weight less of a concern, but the heavier the armor, the less the mobility in more closed environments. The Mark 3 unit fielded in 108 was the lightest version ever made, but that light armor when added to its glitchy sensors left it widely reviled. The Mark 5 that followed was perhaps an overcompensation, but there were a number of Marines who favored its thick shell and improved load-bearing capacity. The Mark 6 is what you’ll recognize from the story. The 41st MEU on the Ticonderoga was the first unit to use them. Though they had significantly lighter armor than the Mark 5, this was offset by the built-in shield projectors, though their use had to be limited or else the power cells would be used up much more quickly.
The HeavySuit doesn’t show up in the main storyline until late in Tico4. The reason for this is that the things are too big to be practical in most applications. They are more than twice the size of a MediSuit, so they can’t fit in ships or inside buildings. They did, however, prove useful as force multipliers on orbital defense platforms. The ground operations in Mars provided another opportunity for HeavySuits to shine, but for the most part, they’re seen as a waste of money, mostly useful for propaganda and PSYOPS purposes.
We’ll stop here because I don’t want to get too much into the postwar years until I start in on the War of the Colonies Cycle. Hopefully you’ve found this illuminating. Maybe I’ll get into superlight doctrine next time. Stay tuned.
