Semper Fi, Congrats! Not sure what FSME is but, I can attest to the STA guys.
I was a sensor operator setting up perimeter and early warning seismic detection, We'd go out with STA and Recon teams to set up our equipment. These
guys kick but!!!
We'll most of them, we had fun with the new boots in P.I.

But I would choose STA over Recon. IMO
