Who Was and Wasn't A Yellowcoat?

I'm watching Stripes and Gladys has been put in charge of the yellow coats.

That is the three guys and the three girls, but Spike, Yvonne and Barry wear yellow coats, too, but she isn't in charge of them.

Do Fred, Ted or Partridge ever wear a yellow coat? I think Ted has, or hasn't he?

Unlikely the other two wear yellow coats at any time.
