I'm all for retractable or otherwise concealable vibranium-based energy weapons integrated with their uniforms, perhaps disguised or doubling as ceremonial decorations for those uniforms. I'd also suggest incorporating a "camouflage" or "chameleon" mode where the uniforms can shift into or pass for other styles or kinds of clothing in the event of an infiltration operation that doesn't necessarily rely on them being outright invisible, just unnoticeable to most people passing by.
