Mission

Task, Purpose, and End State

Bottom Line Up Front

A mission statement has three parts: the task (what), the purpose (why), and the end state (what “success” looks like). Get this wrong and every other factor gets analyzed against the wrong target.

Why Mission Comes First

Every other factor in METT-TC is judged against the mission. A threat only matters if it threatens the mission. A terrain feature is only “key terrain” if it matters to accomplishing the mission. Skip this step or state it vaguely, and every downstream judgment has nothing solid to measure against.

Task, Purpose, End State

Element	Key Question	Example
Task	What exactly needs to be accomplished?	“Move the household to the Cedar Lane cache site.”
Purpose	Why does it matter — what’s the intent behind it?	“…so the family isn’t relying on grid power or municipal water during the outage.”
End State	What does success look like when this is over?	“Everyone at the cache site, vehicle secured, before the 8 p.m. curfew.”

A one-sentence mission statement that combines all three might read: “Move the household to the Cedar Lane cache site before curfew, so we’re independent of grid power and municipal water during the outage.” Notice that this sentence would still make sense to someone who joined the group an hour ago and has no other context — that’s the test of whether a mission statement is actually doing its job.

Specified vs. Implied Tasks

A specified task is stated outright: “move to the cache site” is specified. An implied task is necessary but unstated: getting to a cache site across a flooded low-water crossing implies “find or improvise an alternate crossing,” even though nobody said that sentence out loud. Missing an implied task is one of the most common planning failures, because it never shows up as a checklist item until it’s the thing blocking the route at 6 p.m.

Knowledge Check 1

A MAG’s stated task is “Reach the rally point by 1800.” The only bridge on the direct route is known to flood at high tide, and high tide is at 1730. What has the group actually failed to identify?

A. The end state, since “rally point by 1800” names a location and a time but doesn’t describe the condition the group needs to be in upon arrival. B. The purpose, since the mission names a location and a deadline but never explains why the group needs to reach that specific rally point by that specific time. C. An implied task — finding or improvising an alternate crossing — that the stated task requires but never spells out. D. A Time Available problem, since this is really about the tide schedule rather than anything to do with Mission.

Writing a Mission Statement That Survives Contact

A useful test: read the mission statement back to someone who wasn’t in the room when it was written. If they can’t tell you what “done” looks like, or why it matters, the statement isn’t finished. Vague mission statements (“get everyone somewhere safe”) produce vague plans, because there’s no fixed target to measure a route, a threat, or a deadline against.

Common MistakeConfusing activity with mission.

“Pack the truck” is an activity, not a mission — it doesn’t say why or what “done” means. “Pack the truck so the household can depart within 30 minutes of an evacuation order” is a mission statement, because it names the purpose and the end state, not just the task.

Knowledge Check 2

Which of the following is a complete mission statement, in the task-purpose-end-state sense this lesson describes?

A. “Send someone to the Henderson house before 1800 to verify their status and confirm they have the supplies they need for the next 24 hours.” B. “Check on the Hendersons this afternoon so the MAG has a current picture of their situation and resources before tonight’s briefing.” C. “The Hendersons are two blocks over and haven’t been seen since yesterday — someone from the MAG should swing by and confirm their status before tonight’s 2000 SITREP window closes.” D. “Welfare-check the Hendersons and confirm they have working communications, so the MAG can mark their block green on tonight’s SITREP before the 2000 reporting window closes.”

Lesson 02 moves to the next factor: Enemy and Threats, and the distinction between what a threat will probably do and the worst thing it could do.
