RM Endurance Course
The Royal Marines and RM Reserve complete the same rigorous Commando tests carrying the same weight, and in the same times.
The Endurance course is two miles cross country through water, tunnels and submerged culverts followed by a 4 mile run back to camp. Uniform of the day are boots and utes with basic pack and SA80.
The Enfield is not a rubber duck, so you have to keep your weapon clean and optic intact because once they make it back to camp Marines must shoot and pass a marksmanship test with said rifle.
All in under 73 Minutes
To recap: 73 minutes for 2 miles cross country, 4 miles on road and 1 range shoot.
