What primary role did the Royal Flying Corps serve during its existence?

The Royal Flying Corps (RFC), established in 1912 and active until 1918, primarily served as the aerial component of the British Army during World War I. Its main role was military reconnaissance and support, which was vital for the effectiveness of ground forces. The RFC gathered crucial intelligence on enemy movements and positions, allowing for better tactical decision-making and improved coordination in battle.

Additionally, the RFC provided direct support to ground troops by engaging in aerial combat and conducting bombing raids on enemy positions. This integration of air power into military strategy marked a transformative period in warfare, as the importance of air reconnaissance became evident in the context of the trench warfare that characterized World War I.

The other options, such as naval operations, commercial aviation, and technical training, do not align with the core mission of the RFC during its operational period. The focus on military reconnaissance and providing support in the field was central to the RFC's identity and contributions during the war.
