I think it's about time we give the pentathlon another update

We can replace the pistol with the biathlon rifle.

Swimming and running can stay, but they will do so with 80lb packs on their back now.

Fencing is a bit archaic, we can replace it with something more contemporary. Like room clearing.

In place of show jumping, the event will conclude with a cross-country rally race in a Hummer through a minefield.
