Marked 'Federal' in the original caption, this photograph shows Nicaraguan government troops in firing positions along a courtyard wall, rifles raised in what appears to be a live-fire exercise or combat demonstration. The mixed civilian-military dress of the men, ranging from straw hats to simple shirts and trousers, reflects the irregular nature of many forces armed and organized during Nicaragua's Constitutionalist War and the subsequent U.S.-backed campaign against Sandinista rebels in the late 1920s.
