Any WHOvians watching Supergirl?

earlyre thought this was worth mentioning said
4

3 episodes in, liking the show so far, bit one thing jumped out at me in the first and second eps.....

When the D.E.O. is out doing field ops, they are using U.N.I.T. call signs.
Trap , Greyhound, etc.

I'm sure it's just the writers having a little fun, but kinda interesting..
