I'm not happy about this one, but I've run in to a brick wall so far looking for more info. So I'm going to need some AI-spotters to help me figure this one out, please. Unless of course I'm wrong, and both pics are legit. But I have my doubts...

In any case, this particular AV videotape station allegedly belonged to the US army, and in the 2nd pic, it's a PFC Mathesen who's the particular technician posing.

EDIT: Mystery seems solved thanks to a couple folks below. Evidently these are two genuine photos, likely shot the same day. I remain curious about the first person's uniform though, since it seems so different from the second person's.
