| Go firm | Instruction to stop in place for a long amount of time and therefore to take long-term defenses, such as establishing proper cover, building trenches etc. |
| ARD | All round defense. Instruction to establish security in a full 360° arc. Usually elements/individuals will be assigned to a sector of this defense. |
| Set security ([arc in degrees]) [cardinal direction] | Instruction to take security centered around particular direction for the specified width. e.g. “Set security 180 north”, means hold position and establish security covering West through North, through to East.

If no arc is specified it is 90°. |
