Coast Artillery soldiers conduct a gun drill at a harbor defense fortification in the Philippines, likely part of the Manila Bay defenses, circa the 1930s. Crewmen in fatigue undershirts haul a heavy artillery projectile toward a large seacoast gun still smoking from a recent discharge, while comrades observe from the emplacement parapet above—an everyday scene of the rigorous training that kept these 'Gibraltar of the East' fortifications combat-ready in the years before the Second World War.
