If you traverse a side slope, do it slowly and without turns. Normally, a 30 percent slope is the maximum in good weather. (3) Side slope is even more important than the slope you can climb. If there are four contour lines in any 100 meters, look for another route. If there are two contour lines, it is 20 percent, and so forth. If there is a contour line in any 100 meters of map distance on that route, it is a 10 percent slope. (2) You can easily determine approximate slope just look at the route you have selected. Military vehicles are designed to climb 60 percent slopes on a dry, firm surface ( Figure 12-1).įigure 12-1. It is best to find paths between trees that are wide enough for your vehicle. Vehicles cannot knock down several trees at once. The bigger the vehicle, the bigger the tree it can knock down. (1) Most vehicles will knock down a tree. The navigator must consider this when selecting a route. Swamps, thickly wooded areas, or deep streams may present no problems to dismounted soldiers, but the same terrain may completely stop mounted soldiers. Most military vehicles are limited in the degree of slope they can climb and the type of terrain they can negotiate. When determining a route to be used when mounted, consider the capabilities of the vehicles to be used. Mobility makes it much easier if you get disoriented to move to a point where you can reorient yourself.Ĭonsider Vehicle Capabilities. Having a mobility advantage helps while navigating. Remember that 0.1 mile is roughly 160 meters, and 1 mile is about 1,600 meters or 1.6 kms. You will cover great distances very quickly, and you must develop the ability to estimate the distance you have traveled. When preparing to move, the effects of terrain on navigating mounted vehicles must be determined. The navigator must inform the commander when checkpoints are reached, when a change in direction of movement is required, and how much distance is traveled. For this reason, the navigator must maintain constant communication with the commander. The navigator is responsible for following that route however, there may be times when the route must be changed during a tactical operation. The commander normally selects the route that he desires to use. During movement, any change in direction or distance must be given to the subordinate leaders in sufficient time to allow them to react.Į. Grid coordinates of locations must be recorded and plotted.ĭ. During movement, the navigator must make sure that the correct direction and distance are recorded and followed. It is the navigator’s duty to make sure that all the equipment he may use or require is working.Ĭ. He must do this before the mission starts.ī. The navigator must gather all the equipment that will help him perform his job (maps, pencils, and so forth). The leader should never try to be the navigator, since his normal responsibilities are heavy, and one or the other job would suffer.Ī. The duties of a navigator are so important and exacting that he should not be given any other duties. To be effective at mounted land navigation, the travel speed must be considered. Walking between two points may take one hour, but riding the same distance may only take 15 minutes. The major difference is the speed of travel. The principles of land navigation while mounted are basically the same as while dismounted. To move effectively while mounted, he must know the principles of mounted navigation. If separated from his unit and given an azimuth and distance from their position to his, he should be able to reach the unit and continue the mission. A vehicle commander should be able to navigate from one point on the ground to another with or without a compass.
