[citation needed] An order specifies the instruction to a unit in a structured format that makes it easy to find each specific requirement.
There are a number of subtypes of these field orders, based on knowledge patterns specific to individual military branches.
Most are based on a METT-TC analysis (Mission, Enemy, Troops, Terrain, Time Available, and Civilian considerations).
Administration/Logistics (Service Support in the Army version) V. Command/Signal (Command and Signal in the Army version) Since Marines and soldiers work in small teams, it is important that each member know and understand the order in its entirety so as to be aware of which parts of the order apply directly to them and the subordinate unit to which they belong without being exceedingly aware of minute details provided for general situational awareness.
Generally a sentry knows roughly what time you are coming back at due to the platoon commander informing him.
