More than 3,500 new recruits to the British army pass through its Infantry Training Centre at Catterick Garrison every year.

Infantry soldiers undertake a 28-week training course, designed to teach them the skills required to take part in operations anywhere in the world.

A typical day for an infantry soldier includes drills in bayonet and rifle training, as well as exercises in living in the field, camouflage and adventure training.

To pass, recruits are required to complete "output tests", which include intensive circuit training, and an eight mile march carrying a 55lb pack in two hours.

Drills in bayonet training are considered the climax to the recruits' training, teaching them to fix their bayonets in attack on instinct in the most difficult combat conditions

The bayonet assault course, in which recruits navigate tunnels, barbed wire and rubble while under constant fire, is considered the "ultimate" training challenge.

Many of the soldiers are posted to Iraq and Afghanistan just weeks after completing their training.
