RIO DE JANEIRO, Brazil (July 16, 2009) -- A Chilean Marine looks down the sights of a 240 Bravo machine gun during a demonstration at the assault course training of exercise Southern Exchange 2009 (SE09). Marines who ranged from experienced to new on the machine gun shot through the morning to be familiar enough with the functions of the weapon in case of future use. (Marine Corps photo by Lance Cpl.
