A basic (very basic) skill is simple observation. If you are defending a position or simply making a deliberate move from one position to another you need to carefully evaluate your surroundings before moving out. A simple yet effective method takes 2 steps:
* Step 1. Make a quick, overall search of the entire sector for obvious targets and unnatural colors, outlines, or movements. Look first at the area just in front of your position, and then quickly scan the entire area out to the maximum range you want to observe. If the sector is wide, divide it and search each subsector as in Step 2.
* Step 2. Observe overlapping, 50-meter wide strips, alternating from left to right and right to left, until you have searched the entire sector. When you see a suspicious spot, search it well.
