Radios will fail as soon as you need them. Anything you do will get you shot, including doing nothing. The only thing more accurate than incoming fire is incoming friendly fire. Make it tough for the enemy to get in and you can't get out. When both sides are convinced that they are about to lose, they are both right.
Professional soldiers are predictable, but the world is full of amateurs.
The first time I came across this syndrome was when my father told me about his time spent in a German concentration camp. He was captured in the Battle of the Bulge with General Patton. He told me they use to march the Jews out to the pits and make them all watch as they machine gunned them down and bulldozed them over . Really busting their balls. My father carried a picture of a friend who was shot in front of him for many years.
