My favorite armor from the Halo series: Semi-Powered Infiltration Armor

I'm a Halo fan, have been since the original. This extends to the novels, one of which - Ghosts of Onyx by Eric Nylund - introduced me to this bad boy right here, the Semi-Powered Infiltration or SPI armor. It differs from the MJOLNIR armor worn by Master Chief and other Spartans in the games and novels in that it isn't as heavy and lacks features of the former. It doesn't have shields, no built-in capability to carry an AI. It is, however, mass producible, unlike the MJOLNIR-series, and has a pretty sweet camouflage system.


The SPI was created for the Spartan-III program, the next generation of Spartans. The MJOLNIRs were hugely expensive to build and the IIIs were intended to be created in larger numbers and thus, more expendable than their predecessors. Makes a lot of sense, really. Sending a bunch of super-soldiers on near-suicide missions wearing hugely expensive powered armor is just the dumbest idea ever.

Plus the helmet just looks cool.

The reason why I like it is simply because it's realistic. It's camouflage system uses photo-reactive panels built into the surface of the armor to create a low tech (compared to the Covenant's) active camo system. In the real world, researchers are developing similar technology. It also isn't overpowered like the MJOLNIRs, which will literally crush the bones of any unenhanced human who tries to use it. If I were creating a futuristic military for a sci-fi story, this is the kind of body armor the soldiers would wear.
