bridge 7.3m long; and a 5m long maze. The maze is one of the newer obstacles and replaced a low knee high bar which could be either vaulted over or crawled under. Both British designs are adjusted to fit the available space and terrain features, obstacles are built between 5 and 10 yards apart, not all obstacles are always used, and obstacles from Type A (Trained soldiers) may be used in a course at a Training Camp, for example the Assault Course used by British Army recruits at Pirbright has 10 obstacles, including a maze, 2 dry ditches and a cargo net, whilst the Assault Course at Worthy Down Camp has only 8 obstacles. The Royal Air Force uses the British Army designs, and has Assault Courses at RAF Honington, RAF Halton, and the Royal Air Force College at RAF Cranwell. HMS Collingwood, a Royal Navy, shore establishment has an Assault Course with suitable naval themed obstacles, it has water obstacles which are crossed with ropes and pulleys, as well as a wall to climb over and pipes, on a slope, to crawl up. HMS Raleigh (another RN shore establishment) also has an Assault Course. The German Armed Forces’ Obstacle Course, 'Hindernisbahn-Bundeswehr', has 12 obstacles: a barricade of logs about .6m high; a log on 1.3m high metal post to roll over; 7 log steps to a height of 2.5m; 6 X shapes to climb over – like the US Army’s Tough Nut; 2 bar vault, the first bar .5m high, the second bar is .3m further and .8 m high; 2m high wooden wall; .5m vault, with a .5m deep ditch on the far side; balance log over a wide ditch; low wires to crawl under; trip wires to step over; a 1.8m deep and 1.8m wide trench to climb in and out of; a fox hole from which dummy grenades are then thrown at targets. The former country of the German Democratic Republic’s (East Germany) standard Sturmbahn (storm course) was 200m long and had the following obstacles: 1: 20m of 10 thigh high bars to step over or 6 concrete-semi circles to crawl under. 2: Ditch 2 m wide. 3: Climb a 3m rope to a 15-20m long horizontal rope and then climb down. 4: Climb a 2 m wall. 5: Climb onto the side of a pipe, jump onto a small platform, and then onto the side
