Core Definition (BLUF)
METT-TC is the standard set of mission variables used to frame a tactical problem: Mission, Enemy, Terrain and weather, Troops and support available, Time available, Civil considerations. Some current usage adds (I) Informational considerations. If you cannot brief METT-TC cleanly, you do not understand the job yet.
Doctrinal Framework
- Pubs: Army operations and intelligence doctrine (ADP/FM 3-0 family; applied throughout mission analysis and IPOE/IPB practice)
- Echelon: tactical; pairs with operational variables PMESII-PT
- Coverage: full as a frame; partial on any single variable’s deep TTP
Mission variables describe the situation relative to a mission. Operational variables (PMESII-PT) describe the environment more broadly. Both feed mission analysis in Detachment Mission Planning and Troop Leading Procedures.
Mechanics
Work the letters when receiving a mission; revisit them when the situation shifts.
| Variable | Question |
|---|---|
| Mission | What task and purpose? Who is higher intent? What is the end state? |
| Enemy (or adversary) | Who opposes this? Capability, intent, most dangerous / most likely COA? |
| Terrain and weather | How do ground, built environment, light, and weather help or hurt each side? |
| Troops and support | What people, skills, gear, enablers, and higher support exist in fact? |
| Time | How long until execution? How long does the adversary need? Where is the time fight? |
| Civil considerations | People, structures, organizations, events that shape the battlespace (ASCOPE) |
| (I) Information | Signatures, narratives, networks, data that change the fight |
Product of a METT-TC pass is not a novel. It is a short brief that drives options, recon tasks, and risk.
Application
At mission receipt:
- Restate the task in task/purpose form (Mission).
- Name the adversary set and initial MLCOA/MDCOA (Enemy).
- List decisive terrain: chokepoints, venues, approaches, digital surfaces (Terrain).
- Inventory true strength - not fantasy manning (Troops).
- Build a timeline backward from H-hour or delivery (Time).
- Flag civil, legal, and informational constraints early (Civil / Information).
- Issue recon PIRs that close the largest METT-TC gaps.
Empty cells become collection tasks. A METT-TC frame that never updates after contact is a historical document, not an estimate.
Related Concepts
Wide lens: PMESII-PT (operational variables).
Civil depth: ASCOPE.
Process homes: Troop Leading Procedures, Detachment Mission Planning.
Feeds: Urban Reconnaissance, Center of Gravity.
Failure Modes
- Skipping Enemy because it feels dramatic - then surprise.
- Inventorying Troops as wishful org charts.
- Ignoring Time until the plan is beautiful and late.
- Treating Civil as optional color - then the population or platform kills the plan.
- One-and-done METT-TC - variables move; the frame must be a living estimate.
