(unless I'm mistaken this is the first standalone addon armor pack for CoseaMT's TACZ Juggernaut Armoury mod!)
"the Heavy Counter Assault Space Suit (or HCASS) is a heavily armoured spacesuit meant for extreme conditions on planetary surfaces with a vacuum or non-oxygen atmospheric environment. The HCASS line of armor eats bullets for breakfast without compromising your suit's atmospheric integrity, perfect for base raids or frontline combat." -user manual from the factory, circa 20XX
This is pretty similar to your typical TACZ gun pack; just shove it in the TACZ folder!
Do note that a seperate datapack is required to get it to function as a spacesuit, and I have yet to figure that part out without making EVERY other juggernaut suit into a spacesuit (this has to do with how the mod does suit tagging, similarly to TACZ guns)
Even then, on its own its super rad.
