Whew, should have picked Intel. Anyway...
While in the Army, recently, I always carried some kind of knife and was definitely the unit "knife guy." Occasionally when on TDY I'd get weird looks from folks who didn't know me.
Take a Spyderco Endura to Basic, but don't let anyone know you have it. Keep it clipped to the inside your BDUs, or sew a special pocket in them while sitting on the can during fire guard. IET (Initial Entry Training) is a no knife environment. Just be careful. Went through many a shake down during AIT with a Spyderco clipped in my PTs.
Active duty always carried two folders, but usually an OTF auto plus an auto folder. Carried a MT Halo 1 in a shoulder rig for a while, then switched to Halo 2 in the horizontal rig.
In the field most Commanders are scared that someone may get hurt, so they discourage big blades, not to mention they tend to get caught on stuff while riding on your LBE.
My two bits would be save your pennies and get a MT DA SOCOM. You'll be happier in the long run.
