Iraq in 2007 was my last "combat" deployment. I am in Comm, I operated a relay station for the Predators to send their video back stateside in near real time, so I never left the base... Carried a CRKT M-16 with titanium handles, and a Kershaw Chive. Also a Gerber multitool till I broke the screwdriver (actually trying to turn a screw with it funny enough), replaced it with a Leatherman Surge.
In Korea, I carried a few different items. Started of with a CRK Small Sebenza, but ended up trading it out for a Sage 2, then a BM 710, then a Spyderco PM2, and finally a CRKT Eros once it was office only time. Had a Leatherman Charge the whole time.
