Meh, that's up there with the best we can do and an Octopus is still miles better without even trying - can you build and don such a suit tailored exactly to your current environment in a matter of seconds?

Great until thermal detection is used: “the warmth of the heavy suit can make a wearer stand out more than a standard soldier when viewed”

An octopus won't show up on thermal imaging?

Water is infrared opaque for the most part!
