Our take on Combined Arms Operations Series

The operational focus trades individual soldier stories and close-up tactical control for managing formations, reserves, and battlefield-wide plans. Larger scenarios can also extend across several days, unlike smaller engagements.

What is Combined Arms Operations Series?

This operational strategy game simulates hypothetical battles between World War II armies across national boundaries and historical periods.

Players command German, Soviet, American, British, Italian, or French forces, reorganizing divisions and combining units into custom battlegroups. Simultaneous turns require commanders to adapt as the battlefield changes. Combat includes armor, infantry, artillery, aircraft, reconnaissance, fortifications, minefields, paratroop drops, and amphibious invasions. Scenarios range from small engagements between a few divisions to sprawling army-level battles involving hundreds of units. Play options include single-player, synchronous head-to-head multiplayer, and two-player co-op. Multiplayer partners can coordinate orders in real time and transfer control of units between players.
