BBA102 - Walking RadiomanThis GI is 'humping' the SC 300 BC1000 man pack radio usually reserved for infantry platoon headquarters. This radio set was known as the 'walkie talkie' while the hand held SCR 536 BC611 was nicknamed the 'handie talkie'. Radiomen usually carried a lighter weight personal weapon sometimes a 1911 Colt Automatic . 45 pistol or, more commonly, the M1 Carbine as is shown here.
