re: Are the US/Russian systems alike?
The US EMU Spacesuit comes in different pieces: a torso, the legs up to mid belly, the helmet, the gloves.
The arms can be replaced, I believe, by smaller models.
The spacesuit needs lower atmospheric pressure than sea-level.
The gloves allow for much more dexterity than the Russian spacesuit.
There are lights and TV cameras near the helmet.
