I suggested that it could inject “ecto-cleanser” in case of an accident. It was a pee-tube for air force pilots, but I personally don't think the GB's used it for that. They don't have any container for the pee to go into, if they did, then I'd agree. Only my opinion though, but it's like saying that the jumpsuits are for airforce pilots, therefore that's what the GB's use them for. . .I think the tubes serve a different purpose, one specific for ghostbusting.
