I'm not sure they fought with quarterstaffs or rapiers in WW1.

The boxing and jiu jitsu perhaps.

Apparently swords were used in the war.

Hitting each other with sticks seems like something people at war would do ;-)

Not exactly the same, but this guy made a longbow kill in WW2:

Ehh… a quarter staff is a good approximation for a lot of weapons of convenience. It also teaches gauging distance in a way that translate to boxing.
