Think lightweight and unobtrusive. Some of the fixed blade suggestions in this thread like the Busse are way too big and heavy.
I would go with a Leatherman and a Adamas. The Adamas sheath is excellent.
One of the first things you do in boot camp is dump most of what you brought with you (including clothes) into a box to be sent home. Do not bring a multi-tool or knife to boot camp. I recall someone who did; he was singled out by the DIs and publicly made fun of. It was not pretty. Envision a skinny, scared kid just out high school being surrounded by multiple DIs screaming at him. I kept a low profile after I witnessed that.
