So, if you aren't IG, how do you get some of your cool gear? I have always wished that a group of IG came with some variety of carapace armor and jump packs, and can imagine a squad of elite Elysian jump troops, but the common answer is "the IG doesn't care, and don't devote such resources on individuals." or some such thing. So, where does, say, the Adeptus Sororitas get their stuff, that no one in the Dept. Mun. complains? In some lights, they shouldn't even exist, with the Ecclesiarchy being forbade soldiers, but it said "men at arms", and Battle Sisters aren't men (which is technically correct; the best kind of correct), with their glorious...Faith, yeah Pure Faith. They get Power Armor, Jet Packs, and all kinds of cool things, but how? Why can't the IG operate several small, super-specialized units, like Jump Infantry? Packs are made at Human scale (Seraphim wear them), but I otherwise don't know why they exist, if next to no one uses them. Fuel could be an issue, but they'd still do more for the Drop Trooper than break one fall, which is what I imagine the grav-chute did. (Now I have an image of IG with the Transformers 3 wing suits.)
I really wish that my 103rd Elysians could be Jump Pack-toting Infantry, rather than just falling out of Valkyries; it would make for a cooler story, if it wouldn't get laughed at incessantly.
