  • 兵隊へいたいJLPT N2approx.Common
    nounGlossed as armed forces, military, or troops like 軍隊, but in practice it commonly evokes soldiers themselves. Often a less precise choice for troops as a formal military force.

    The city was soon occupied by the soldiers.
  • 軍勢ぐんぜいCommon
    nounRefers to military forces or troops as a body of soldiers, and can also mean the number of soldiers. Suits narratives describing an army's strength or a force assembled somewhere.
