CAMP FOSTER, Okinawa — Just in case you spot unusual activity on Marine bases here this week — don’t worry about it.

The extra gate guard and the flurry of activity at a post office or commissary has nothing to do with terrorist threats or the war in Iraq, according to Marine 2nd Lt. Tryiokasus Brown, spokesman for Marine Corps bases on Okinawa. They’re just an annual force protection exercises.

The exercise started Tuesday and will continue through the week with scripted events involving each of the bases. The events range from keeping suspicious characters off the bases to responding to explosions, mass casualties, riots and a hostage situation, Brown said.
