[Milsurplus] Guess what the AN/USS-2A is

[Mike Morrow]

Pardon this trivia, but things are pretty slow on the list.

I just found a manual TM 11-5530 (Jan 1952) for a portable piece of vacuum
tube gear called the AN/USS-2A.  It describes the most unusual purpose
military electronic equipment I've ever seen.

Anyone care to identify or guess its purpose?  (Answer is below)

I guess the US military must have bought in to unscientific BS-based
hocus-pocus just like our intelligence and police agencies always have,
because the AN/USS-2A is a portable Lie Detecting Set!

If the military was wasting money on that sort of witch-doctor mumbo-jumbo
50 years ago, then maybe there's a military manual out there for a
communication set designed to provide a psychic hot-line between field
commanders.
