All-round defense
All-round defense in combat means securing in all directions. To do this, different positions are taken depending on the tactic. While the regulations of the 18th century still provided for “squares for all-round defense”, the soldiers of the 21st century spread out over the terrain using optimal cover, but only so far that the soldiers can still maintain line of sight. In this way, the soldiers secure from the center of the split-up squad to the outside against enemy action.
Modern battle tanks have electronic concepts of all-round defense; an example is the MUST .
