4405th ACFT GEN SQD Patch [Series V-VI]

The 4405th ACFT GEN SQD patch can first be found in place of the Federal Marshal pin on Lister's screen-left leather jacket lapel. A full series-on, and it has not only leapt onto Lister's fur-lined leather cap, but also the screen-right section of his leather waistcoat.

Perhaps, two patches being present hints at some unseen follow-up experiment with the Triplicator, in which one of its three matter paddles shorted-out, merely duplicating the object? Or, maybe Lister just found two of the same patch in storage. In fact, where did all of these pins & patches originate? Probably, a drawer. But, I'd like to think there was a militaria or antiques shop tucked away in the ship's mall, somewhere.

In other news, I so far haven't been able to glean a great deal regarding this particular squadron, though I understand that 'ACFT' refers to 'Army Combat Fitness Test', which certainly lines-up with the daring slogan, "FIT TO FIGHT".
