How To Build An Army in Civilization 6

Building a powerful army in Civilization 6 requires understanding the game’s unit combination mechanics. By unlocking specific civics and following a strategic progression, you can merge individual units into increasingly powerful formations. This guide walks you through the exact steps to create armies in Civ 6.

Step 1: Unlock the Nationalism Civic

The foundation for building armies starts with acquiring the Nationalism Civic. This civic is essential because it unlocks the ability to combine units into more powerful formations. Once you have the Nationalism Civic, you’ll be able to form two identical units into a corps or fleet.

Step 2: Obtain the Mobilization Civic

After securing Nationalism, your next objective is to research the Mobilization Civic. This is the key civic that enables you to form three identical units into a full army. The Mobilization Civic represents a significant military upgrade in your civilization’s capabilities.

Step 3: Form a Corps (Two Units)

To demonstrate the process, let’s use Rangers as an example. Position two Rangers next to each other on the map. Once they are adjacent to one another, you’ll notice a “Form Corps” option appears in the bottom right corner of your screen.

Click on this option and select the second Ranger from the menu. This action will merge your two Rangers into a single Corps unit, which is more powerful than individual units.

Step 4: Form an Army (Three Units)

Now that you have a Corps, obtain a third identical unit—in this case, another Ranger. Position this new Ranger next to your Ranger Corps.

Once positioned correctly, a “Form Army” button will appear in the bottom right corner of your screen. Click this button and select the Ranger to merge your Corps with the additional unit.

The result is a Ranger Army—a significantly more powerful military unit than the individual Rangers you started with. You’ll see the confirmation on your screen labeled “Ranger Army.”

Summary

Building an army in Civilization 6 is a straightforward process once you understand the mechanics. First, research the Nationalism Civic to unlock Corps formation, then research Mobilization to unlock Army formation. Combine two identical units into a Corps, then combine that Corps with a third identical unit to create an Army. This progression allows you to create increasingly powerful military units that can dominate your opponents on the battlefield.
