noun
mounted corps; cavalcade
Refers to a group of people on horseback, often in a military or ceremonial context. The term is somewhat formal and not an everyday word.
式典では乗馬隊がパレードを行った。

Compound of 乗馬 (じょうば, 'horseback riding') and 隊 (たい, 'group, corps'). The exact historical derivation is uncertain, but the term follows standard Sino-Japanese word formation.
