Army Commander Craft mixes base-building with combat: between battles you construct and upgrade your forces, and in battle you command them against an enemy army. Success depends on both halves — a well-built army fights badly if commanded poorly, and good tactics can't rescue an under-built one.

Both — you build and upgrade an army between battles, then command it in combat. The building half decides what you have; the commanding half decides what you do with it.
Mix unit types so you aren't hard-countered, and concentrate your force rather than attacking on a broad front.
