Just an extra thought.
I was watching Waltz (Deep Space Nine, Season 6), the one where Sisko and Dukat are stranded on a planet and the Defiant is sent to look for them.
The Defiant was working on a limited timescale as it had to rendez-vous with a Federation Troop Convoy containing 20,000 troops en-route to the frontline from the Badlands.
I think this would settle any argument about whether or not there is any troops in the Federation given that they are referred to clearly in the script of an episode (can't get more cannonical than that).
Just a thought.
We have all your working biros and we're not afraid to use them.
Leave a box of used postit notes and a box of paperclips inside the filling cabinet and things won't get nasty.
Yours,
