over under bars; 4 steps; and a 3 m high ramp with rope. Whilst ideally 250m long, the course can be between 150m and 300m long dependant on available space. The standard French military Assault course is 500m long and has the following 20 obstacles: 5m high Rope Ladder; Double Beam 1 and 1.4m high; 6 Trip Wires 0.6m high 2m apart; 20m long Low Crawl under 0.5m; 5 Stepping Stones; 3 Bar Vault 2.3m high; Balance Beam 1m high and 8.5m long; 5m high Vertical Ladder; Over and Under Beams 1.2m and 0.7m high; 2m high Irish Table; 0.8m high Low vault; 0.5m deep ditch; Ramp and Ditch; 1m Low wall; 0.7m deep ditch a 1.5 High Bund and a 0.7m Ditch; 2m High Wall; 2.2m deep Pit; 4m high Climbing Wall; 8m long Chicane; 3 Trenches the first narrow and 0.85 deep, the second 4m wide and 1.1m deep, the third narrow and 0.85 deep. Many of the obstacle are similar to those on the CISM (International Military Sports Council) obstacle course used for Military Pentathlon such as the Irish Table which is a plank 2m above the ground which requires both technique and strength to overcome. The 4m high climbing wall is particular to French assault courses and also requires good technique to climb. The British Army has two standard designs. Type A, for trained soldiers and Type B, for training establishments. Type A, the design for trained soldiers has 18 different obstacles, and is usually wide enough to allow two teams to compete. The design includes: 4 steps up to 1.7m; monkey bars 5.4m long and 2.8m high; stepping-stones; 5.8m high cargo net; 10m long pipe crawl; rope swing over a 6.7m wide ditch; 4m high OBUA (Operations in Built Up Area) double wall with ladders up and between the walls with window openings; and 8m high climbing ropes. Type B, the design for British Army training establishments has 9 different obstacles. Most obstacles are built with 3 levels of difficulty: the vault has heights of 1.2m, 1.5m, and 2m; the high wall has heights of 2.1m, 2.5m and 3m; this allows the recruit to progress form easier to more challenging versions of the same obstacle as they progress through their training. The design also includes ramps; ditches wet and dry; ropes and ladders to climb up 4.8m and then cross a rope or a rope
