Dozens of Marines will be raiding buildings and shooting paintballs at each other in downtown Los Angeles to prepare troops for urban combat.
Capt. Brian Block said Thursday that the raids at several undisclosed locations in the city will be off limits to the public.
Block says the trainings are part of a two-week military exercise that starts Friday and involves about 2,400 Marines and Sailors from the 15th Marine Expeditionary Unit.
He says the Los Angeles portion will take place over a couple of days next week. The other exercises will take place at military bases in California, at a site outside Las Vegas and at an undisclosed location in Arizona.
Block says there are no residents living in the training sites but the helicopter noise may be noticeable.
