Military maneuvers in Sid Meier’s Civilization VII resolve the notorious 1UPT (one unit per tile) traffic jam that plagued Civ V and Civ VI. In previous games, moving large late-game armies required dozens of individual tedious move commands, creating carpet-of-doom bottlenecks across mountain passes. Civ 7 solves this through the revolutionary Commander Unit system—a tactical framework that allows generals to pack multiple combat regiments into a single mobile army tile.
What this covers: Commander packing capacity, Packing and Unpacking army mechanics, Commander promotion trees, and combat aura bonuses. Why it matters: Commanders allow entire packed armies — up to four military regiments and a civilian at once — to march across continents on a single movement order without blocking friendly roads. Who should pick this: Generals waging multi-front wars across continental landmasses.
How Commander Stacks Operate
Commanders are unique military leadership units that can absorb standard combat units (infantry, cavalry, siegesiege. A timed, large-scale attack on a settlement — attackers try to destroy it, defenders try to hold it. engines) directly into their command retinue. By default, a Commander packs up to 4 Military Units and 1 Civilian Unit — limits specific Promotions can raise — and their bonuses reach every unit packed inside or standing within the Command Radius, which covers the Commander’s own tile and all adjacent tiles and expands through Commendations:
| Army Action | What It Does | Movement Cost |
|---|---|---|
| Assemble Army | Packs the Commander guard and all adjacent units into the Commander | Does not deplete movement; usable repeatedly |
| Deploy Army | Deploys all packed units simultaneously, prioritizing melee at the front and ranged or siege at the rear | Consumes all movement from the Commander and the deployed units |
| Add To Army | A unit with movement remaining joins a nearby Commander with open slots | Does not consume movement |
| Leave Army | A packed unit deploys to the current or an adjacent eligible tile | Consumes the unit’s movement, not the Commander’s |
| Reinforce Army | Sends a unit from any location to join a selected Commander, vanishing from the map en route | Arrives after the number of turns the journey would normally take |
While packed inside the Commander, individual regiments cannot be targeted directly by enemy ranged fire. The entire army moves as one cohesive piece, drastically reducing late-game turn times.
Packing and Deploying on the Battlefield
To engage in tactical combat, the Commander executes an Unpack action:
- March Phase: The Commander travels packed across open roads and plains at maximum transit speed.
- Engagement Phase: Upon reaching the enemy border, activate Unpack. The Commander expends movement to deploy all packed regiments into adjacent hex tiles in optimal tactical formations (spears forward, archers in rear).
- Flanking Auras: While unpacked, regiments fighting within the Commander’s visual aura radius receive substantial attack and defense multipliers.
Commander Promotion Trees
As Commanders participate in battles, they earn experience points and invest them in specialized promotion trees — raising a Commander to 8 Promotions is itself a Major Triumph. Army Commanders choose among five core trees:
| Tree | Focus |
|---|---|
| Bastion | Defense — enhances Combat Strength and healing of land units and fortifications when defending |
| Assault | Offense — enhances Combat Strength of all land units when attacking |
| Logistics | Sustainability — increases unit training speed, decreases maintenance costs, upgrades unit slots, and enhances healing in enemy territory |
| Maneuver | Mobility — enhances Movement, terrain combat, and flanking bonuses |
| Leadership | Commander competence — increases yield generation when garrisoned, enhances Combat Strength of command group attacks, and allows healing and promoting in enemy territory |
Reaching the top tier of any tree awards a Commendation Point, spent on unique upgrades that expand the Command Radius, unlock powerful active abilities, or passively boost every unit in range. Specific commanders bring unique trees of their own, and bombardment is a Fleet Commander specialty (the Bombardment and Engagement trees) rather than an Army option.
Commander Types Across the Ages
Not every Commander is the same unit class. The families unlock in sequence and operate differently:
| Commander | Available From | What It Commands | Notes |
|---|---|---|---|
| Army Commander | Antiquity Age | Land Units | The default field commander; packs land units only |
| Fleet Commander | Exploration Age | Naval Units | Packs naval units only; owns the Bombardment and Engagement trees |
| Aerodrome Commander | Modern Age | Aircraft | Spawns automatically on an Aerodrome; immobile |
| Squadron Commander | Modern Age | Aircraft | Can create a temporary airbase; unique Airlift Operations tree |
| Aircraft Carrier | Modern Age | Aircraft | The only mobile aircraft commander; unique Carrier Operations tree |
Two rules govern packing across these families. First, a Commander can only pack units of its own element - an Army Commander takes land units, a Fleet Commander takes naval units, and cross-element packing such as loading ships into an Army Commander is impossible. Second, Aircraft Commanders sit outside the packing system entirely: they are stationary operators that hold air units at a base rather than transporting them across the map. An Aerodrome Commander is spawned on top of a completed Aerodrome and cannot be rebased; air units assigned there grant the base 4 Sight while stationed, and if the airbase is destroyed the Commander is eliminated and its aircraft attempt to rebase, or are removed from the game if no eligible base is in range.
Promotion Mechanics: Where Experience Comes From
Promotions are Commander-only in Civ VII - ordinary military units never gain them. Commanders earn experience when units they command fight inside the Command Radius, which by default is the Commander’s own tile plus the six adjacent tiles and expands through bonuses such as the Merit commendation. Four rules shape how fast that accrues:
- Element matching. A Fleet Commander gains experience only from naval combat; air units grant experience to the Aircraft Commander holding them when they attack.
- Experience splitting. If multiple eligible Commanders are in range of the same fight, the experience is divided between them.
- Diminishing returns. The threshold for the next Promotion rises with each level, and farming weak units eventually yields as little as 1 XP. Dispersing Independent Powers always pays a large experience bonus instead, which makes them the reliable training target.
- No penalty for hoarding. You can bank unassigned Promotion points and spend them later.
A Promotion point is spent through the Promote action, which is normally only allowed in friendly territory unless a specific ability says otherwise. Promoting does not consume remaining Movement, so a Commander can level and immediately promote in the same turn. Because the thresholds climb, the practical route to the eight-Promotion Major Triumph is a mix of real wars and Independent Power clearing rather than one long grind against a single rival. A handful of civics and wonders shortcut this entirely: Grande Armee hands every existing and future Commander a free Promotion point, Commissioned Officers adds 30% Commander experience, and Antonio Lopez de Santa Anna grants enough experience for five Promotions at once.
Commendations and Specialization
Every tree hands out exactly one Commendation Point when you reach its top-tier Promotion - no more, no matter how many top-tier nodes that tree contains. Commendations are the elite tier of Commander power: they expand the Command Radius, unlock active abilities, and passively buff every unit in range. That structure pushes toward concentrating points in a single tree so the Commendation lands early, though the wiki advises that spending a few points on utility nodes first is a reasonable detour. The five core Army trees are not the only ones in the game; specific commanders bring unique trees of their own, with Trung Nhi’s homeland-defence tree as the clearest example, and the aircraft branches add Airlift Operations and Carrier Operations.
Commands, Auras and the Command Radius
Being “under command” means one of two things: the unit is packed inside the Commander, or it stands within the Command Radius. Radius matters for Army and Fleet Commanders specifically, since they are the ones directing units on the map - Aircraft Commanders work through their airbase network instead. Within the radius, a Commander issues Commands, coordinated orders that trigger eligible units simultaneously and, unusually, let units act even after they have spent all their Movement points. That is what makes a late-turn Command the tool for a surprise push, and it is separate from the passive stat aura the radius already projects. Every Commander starts with a basic set of Commands, and more are unlocked through certain promotions or Commendations.
Vulnerability, Death and Carry-Over
Commanders are classified as Civilian Units, so they cannot attack, but they can be attacked and damaged, and they can share a tile with a military unit. That sharing unit becomes the “commander guard” and absorbs damage first - which is why an unguarded packed Commander is a serious liability: enemy attacks land on the Commander and the packed units inside it, not on a buffer. The Commander wiki records a 20-turn respawn window before a defeated Commander returns to the field, which is a real setback but never a permanent loss.
The Age transition is where Commanders pay off most. Ordinary units are culled when a new Age begins, but Commanders are never removed, their attributes and experience carry forward, and each surviving Commander protects up to four additional units from deletion. That makes a promoted Commander the single most reliable way to carry a veteran army’s value across an Age boundary, and it is why “Have a Commander with 8 Promotions” sits among the Major Triumphs rather than the Minor ones.
Reading the Packed Army in Combat
Because deployed units follow the real algorithm - melee at the front, ranged and siege at the rear - the shape of the unpack tells you where the fight will happen. Two practical consequences fall out of the movement-cost table above. Deploy Army consumes all Movement from both the Commander and every deployed unit, so unpacking in contact with the enemy can leave you unable to reposition unless a Promotion such as Initiative or Weather Gage removes that cost; the same promotions enable Commander hopping, where units move in and out of the stack without losing Movement and can effectively slip past an enemy Zone of Control. Add To Army and Leave Army are far cheaper for the Commander - Leave Army costs the departing unit’s Movement but not the Commander’s - so you can empty a stack and still act with the leader in the same turn.
That mix of cheap packing and expensive deployment is the real skill of the system: march packed, keep the Command Radius and its bonuses live as you approach, and only unpack once the formation you place is the formation you want to fight in.
