To merge units into an existing army in Ashes of the Singularity II, select the units you want to transfer and press Ctrl + the destination army’s number. That is the shortcut documented for the February Next Fest demo. Check the destination number first, especially if you are combining forces after a retreat or regrouping near the front.

Merge units into an existing numbered army

  1. Identify the army that should receive the units. A single tap of its number selects that army, so use this to confirm you have the intended destination.
  2. Select the units you want to move into it.
  3. Hold Ctrl and press the destination army’s number.
  4. Select the receiving army and check its composition before giving the combined force another order.

The February Ashes II hotkey list documents the numbered merge shortcut. If your current build behaves differently, check its controls before repeating the command.

Use the moving-army command when appropriate

The same list documents Alt + right-click with multiple units selected as a context-dependent command that merges or splits units into a moving army. If you already know which numbered army should receive the selected units, Ctrl + number is the more direct choice. Use the moving command when the intent is to reorganize the selection and move it, then check the resulting army.

Choose what to combine before a fight

A merge is useful when two weakened forces need to fight under one set of orders. If one force is still scouting while the other is defending a position, there is a reason to keep them separate. Review what each army needs to do next before you combine them.

After the merge, give the units time to come together before committing to an attack. The May developer journal describes army movement as a shared route with individual units finding their own paths into formation. A combined selection does not mean every unit is already in position.

FAQ

Does pressing the army number alone merge units?

No. In the documented demo, pressing the number once selects the army. Hold Ctrl while pressing the number to merge the selected units into it.

Can I merge only part of my force?

Select the units you want to transfer before issuing the numbered merge. Check the selected units first so you keep any units that still have a separate task.

Why should I check the army after merging?

The army’s composition and the units’ physical positions are different things. Checking both helps you avoid advancing while some of the units are still catching up.
