Passive powers will provide a constant boost to your armies once unlocked while active powers need to be used from the radial at the expense of supply and/or power resources. You can spend these in the leader power radial (accessed with the Left Trigger) to unlock active and passive leader powers. During each campaign mission and multiplayer match, you'll earn leader points. Leader Powers are your most powerful weapons in the game. As a general rule, you should aim to have a good mix of unit types, but beware of what your enemy is using. Certain units break these rules - these are counter units, which have an edge against specific unit types, but are dangerously weak against everything else. Most units in Halo Wars 2 have a rock-paper-scissors relationship with each other, i.e., vehicles are effective against infantry, air units are effective against vehicles and infantry are effective against air units.

Though there are two factions in Halo Wars 2, both armies work in similar ways. As a general rule, if you have enough supply, you'll always be able to field a competent army and, with enough power, you can make that army more lethal and focus on your strengths. Power is used to purchase upgrades for units, buildings and is an addtional cost for certain units. Supply is required to purchase buildings, train core units, and is the primary cost of most specialist units.

You can gather these by constructing certain buildings in your base or by collecting them from objects in the levels. The core of the economy in Halo Wars 2 are supply and power. The battle dynamics will frequently change on the fly, so knowing the basics will help you to adapt and react. In Campaign, Multiplayer and Skirmish, you'll have balance managing your economy, army and leader powers as you take the fight to the enemy. Halo Wars 2 is an action-RTS (real-time strategy) game.
