In my 20's I worked with a guy that was trained on that system mounted to a carbine in Korea. He hated every minute of it. Had to go out on every night patrol while everyone else rotated. It weighed a ton even on the carbine and the battery was a "sealed" lead acid car battery. When I asked why a carbine and not a Garandhe told me most guys couldn't lift it to their shoulder to aim it mounted on a Garand which they had a set up at the school. He also said it wasn't worth the effort because you couldn't really see at long range so the Garand advantage was nullified.
