Going by the International Code of Signals, which single flag is interpreted as "I require assistance (not distress)"?

The story behind the answer

Victor is correct because, in the International Code of Signals, the single-letter flag V specifically means “I require assistance (not distress).” It’s a white flag with a red diagonal cross (a red saltire). True maritime distress is signaled differently—most commonly by SOS in Morse or by hoisting November over Charlie (NC), which means “I am in distress and require immediate assistance.”

Context helps avoid mix-ups: Delta means “Keep clear; I am maneuvering with difficulty,” Kilo means “I wish to communicate,” and Papa means “All personnel return to ship.” Memory tip: think “V for assistance” like the ground-to-air rescue signal where a large “V” on the ground means “require assistance,” and picture the red cross-like saltire on Victor as a visual cue for help without full distress.
