Players command Allied forces on a hex map, planning advances that stay inside a supply network they have to capture and repair.
Why it may be useful
The game refuses to let a unit function beyond its supply line, so you learn the constraint of distance and capacity by losing to it rather than by reading about it. Tied to one campaign, one side and one war, none of it travels much further than that.
Keep in mind
It is a clean operational puzzle about one side of one war, and the human cost sits entirely off screen.

What the game is
Unity of Command II is an operational wargame by 2x2 Games, made with Croteam, out since 2019 on Windows, macOS and Linux. It is small by the standards of the genre: a scenario takes an evening, the map is a clean hex grid with tidy unit counters, and the interface fits on one screen without nested panels.
The campaign follows the Western Allies through the Second World War, with branching outcomes so that how well a scenario goes changes what comes next and what resources arrive with it. Between missions you spend a limited pool on headquarters, specialists and theater assets such as air support or sabotage behind the lines.
What makes it unusual among wargames is that combat is the simple part. Every unit draws supply back along a chain of roads and railways to a source, and the chain has capacity and can be cut, repaired or overloaded. A strong division at the end of a thin supply line is not a strong division. The fog of war is handled the same way, through reconnaissance and captured prisoners rather than through a revealed map.
What you actually do
A turn is a plan about distance. You look at where you want to be in three turns, then work backwards through whether the railhead can be repaired that fast, whether a captured town restores the chain, and what happens to the spearhead if it does not. You commit specialists and air support to the one place they will change the outcome. Attacks are resolved on the hex grid with clear odds, and the interesting decision is almost never whether to attack but whether the unit that wins the attack can be kept fed afterwards. Getting better means recognizing an overextension before you make it, and reading a map for its roads rather than its front line.
What it exercises
Reads a map for supply routes and capacity rather than for frontage
Plans several turns ahead and works backward from the goal
Recognizes overextension before committing to it
Spends a scarce pool of support where it changes an outcome
Draws conclusions from incomplete information and seeks the missing piece
Why we rate it Moderate Worksheet score 56 / 100
FitHow much real knowledge or skill does the play itself make you use?55weight 45%
At 55 the game refuses to let a unit function beyond its supply, so the constraint is learned by losing to it rather than by being told about it, which is real. It settles mid-table because the game reduces military operations to one lever, supply distance and capacity, and leaves out intelligence, morale, terrain friction and the dozens of other factors a real campaign has to weigh.
TransferWill what you practise here work outside the game?45weight 30%
At 45 the idea that a plan is limited by what can actually reach the front is general and useful, and it is one of the most repeated lessons in real military history. It stops there because everything else is specific: one campaign, one side, one war, and the particular numbers involved do not carry anywhere beyond this game.
PracticeDoes the game make you use that skill again and again, as it gets harder?70weight 25%
At 70 scenarios are short and each one poses the same supply question in a different geography, with a branching campaign that plays out differently on a second run. It stays at the lower end of that band because the campaign is finite: once the scenarios are solved there is much less reason to return than in an open-ended strategy game.
What the evidence says
Editorial onlyNobody outside our desk has checked this. It is our reading of how the game plays.
The evidence level is Editorial only. What is confirmed comes from the Steam listing: the 2x2 Games and Croteam credits, the 2019 release, the list price, the Windows, macOS and Linux support, the Western Allied campaign with branching outcomes, the hex-grid turn-based combat, the supply mechanic, the fog of war through reconnaissance and prisoners, the headquarters system and the theater assets. No study of Unity of Command II was found and none is claimed. The case made here is an editorial reading of a design that makes supply the binding constraint, not a measured effect on historical understanding.

Why it makes the cut
A commercial wargame sold on the elegance of its scenario design, with no educational framing.
Editorial only
This is our own reading of the mechanics, based on the current Steam listing; it confirms the developer, release and reception, but nothing here measures what a player actually understands about logistics.
