‘伞兵’ literally means ‘umbrella soldier’ — a compound noun formed from 伞 (sǎn, ‘umbrella’) and 兵 (bīng, ‘soldier’). Though the character 伞 evokes an umbrella, here it refers specifically to a parachute, making ‘伞兵’ a paratrooper: a military soldier trained to descend from aircraft using a parachute and engage in combat after landing. The term emphasizes the method of deployment rather than equipment alone.

This word is used almost exclusively in military, historical, or news contexts — for example, describing elite airborne units, wartime operations, or training exercises. It carries formal and technical connotations; you won’t hear it in casual conversation or non-military settings. While visually suggestive of ‘umbrella’, the meaning is strictly specialized and never metaphorical — confusing it with actual umbrellas is a common beginner error.
