Translation guide
In Japanese, the concept of 'cavalry' is expressed through words that refer to mounted soldiers or units, with distinctions between historical and modern contexts, and between the soldiers themselves and the branch of the military.
Referring to soldiers who fight on horseback, or the unit they belong to.
The cavalry unit charged the enemy lines.
Literally 'mounted horse unit'. Often used for historical cavalry, especially in samurai contexts.
During the Warring States period, cavalry units played an important role.
Specifically 'cavalry unit' or 'cavalry regiment'. More formal and organizational than 騎兵 alone.
He was the commander of the cavalry regiment.
Modern 'armored cavalry' or 'mechanized cavalry', referring to tank and armored vehicle units. Not traditional horse cavalry.
The armored cavalry deployed to the front lines.
Referring to the cavalry as an arm or branch of service, rather than individual soldiers.
Using 'cavalry' metaphorically to mean help that arrives at the last moment, like 'here comes the cavalry'.
Literally 'reinforcements'. The most natural way to express the figurative 'cavalry' arriving to help.
Just when I thought it was over, the cavalry arrived.
Idiom meaning 'timely help' or 'a helping hand', similar to 'cavalry' in a rescue sense.
Literally 'savior' or 'messiah'. Can be used figuratively for someone who saves the day, like the cavalry.
When using 'cavalry' figuratively to mean 'rescuers', do not directly translate it as 騎兵. Instead, use words like 援軍 (reinforcements) or 助け舟 (timely help). 騎兵 only refers to actual mounted soldiers.
騎兵 is the general term for cavalry soldiers or units, while 騎馬隊 emphasizes the 'mounted unit' aspect and is more common in historical samurai contexts. In modern military contexts, 騎兵 is standard.
騎兵は機動性が高い。
Cavalry has high mobility.
