The blurb at the front says some of these things are in use by US government, some aren't. So why does the government's internal catalog list things the government doesn't use? Who would buy those things if they weren't in use? I'm not trying to make a point here, I'm confused.
But the first two are part of the government, so anything they use is by definition in use by the government. Would the other groups get the catalogue? I would think not since it's supposedly internal to the US government...
