GTO Outdoor Obstacles & Bridging Guide: The 4 Golden Rules of PGT, HGT & Command Tasks

### The Role of the Group Testing Officer (GTO) The GTO does not judge candidates in isolation; he observes your real-time behavior in a social setting. In outdoor tasks (PGT, HGT, Command Task, FGT), the objective is to transport your entire group along with a heavy load (e.g. ammo box, drum) across a designated series of obstacles using provided equipment (wooden planks, bamboos, and ropes). --- ### The 4 Fundamental GTO Rules 1. **Rule of Color:** - **White Structure:** Can be touched by both candidates and bridging materials (planks/ropes). - **Blue / Yellow Structure:** Can be touched by candidates only; bridging material CANNOT touch blue/yellow surfaces. - **Red Structure:** Strictly out of bounds for both candidates and equipment. 2. **Rule of Out of Bounds:** - The earth or ground between starting line and finishing line is out of bounds. Stepping on the ground results in an immediate foul, requiring stepping back. 3. **Rule of Rigidity & Tying:** - Planks and ropes cannot be tied to each other to make one long rigid structure unless a fixed support is used. No two loose structures can be tied end-to-end without a grounded anchor. 4. **Rule of Group:** - The task is not finished until all group members AND all assigned equipment/loads are safely across the finish line. --- ### Core Engineering Principles Used in GTO Tasks - **The First-Class Lever (Fulcrum Principle):** Placing a plank across an intermediate support with weight applied at the rear end to cantilever the front end forward. - **The Counterweight System:** Utilizing the body weight of 2-3 group members to hold the anchor side of a plank firm while a scout crosses to the next secure foothold. - **Rope Extension / Lashings:** Using square or clove hitches to secure a plank temporarily to a vertical upright to prevent sliding.
