Military Weapons and Defense of the Canal Zone

Since the opening of the Panama Canal, its defense was a strategic priority for the United States. Multiple military bases and defensive positions were established throughout the Canal Zone, including Fort Amador on the Pacific side and Fort Randolph on the Atlantic. The defense system included large-caliber guns, machine guns, 12-inch mortars, searchlights for nighttime surveillance, antenna fields for communications, and air bases such as Albrook Field.

During World War II, military presence intensified with aerial patrols, airborne troops, and exercises like Operation Barracuda. Marines were deployed at strategic points such as Bas Obispo and Camp Elliot from 1911. The naval fleet also played a crucial role in protecting both entrances to the canal.
