HOI4 Army HQ System Explained

Deploying an Army HQ in Hearts of Iron IV after the Thunder at Our Gates expansion is a short sequence: design a template inside the width cap, attach a commander, and put the HQ on a front line where its bonuses actually reach your divisions. This guide walks that sequence step by step, then covers what an HQ costs, where the commander should stand, and what happens when the enemy captures him.

Quick answer

How to deploy an Army HQ

The order matters, because two of these steps are expensive to undo once the HQ is on the map: the template decides what the deployment costs in manpower and equipment, and the front line you assign it to decides whether the commander's bonuses reach anything at all.

1. Open the Army HQ Designer and start from a templatethis is the only screen where HQ size and battalion type are chosen
2. Pick one battalion type and stay under 8 widthmixing infantry with tanks or mobile battalions is not permitted
3. Use infantry unless the commander needs speed600 manpower and 60 infantry equipment per battalion; mobile battalions often cost more
4. Add support staff before you deployArmy HQs fit a limited number of slots, and each battalion also raises command power cost
5. Assign the commander to the Army HQcommander bonuses only apply to divisions directly under his command
6. Assign that HQ to a front line, not a fallback lineArmy HQs appear assignable only to front lines
7. Place the commander on the line, or one tile behind itfull planning on the line, -5% max planning one tile back
8. Keep the deployed HQ out of combatlosing the commander has significant consequences

The sibling guide on HQ support companies notes that holding shift while assigning a commander to an army also starts deploying his HQ — see HQ support companies: the best Army HQ setup.

Create a cheap Army HQ

Army HQ divisions in Hearts of Iron IV are capped at a maximum combat width of 8. They can only use a single battalion type at a time: mixing infantry with tanks or mobile battalions is not permitted. Infantry HQ battalions are considered elite units and require just 600 manpower and 60 infantry equipment each, making them economical for most purposes.

The main goal is to keep Army HQs out of direct combat, as losing your commander can have significant consequences. Tanks are generally not suited for HQs: they have low organization and hit points, cannot use motorized trucks for added stats, and burn fuel and supply unnecessarily. If you need HQ mobility, you can use mobile battalions (such as motorized) to give your commander speed — but keep in mind this often costs more resources.

The meta for cheap Army HQs in single-player is likely a minimal design: a 2-width setup with two infantry battalions. This minimizes both manpower and equipment expense, while still fulfilling the HQ role. Each battalion added increases command power cost, so it pays to keep the template lean.

1. Open Army HQ Designer0:01
2. Add 2–4 infantry HQ battalionsEach battalion costs 600 manpower, 60 infantry equipment
3. Do not add tanks unless you need mobility or armored HQTank HQs lack org and HP, consume extra supply
4. Use mobile battalions for speed if neededMotorized HQs allow faster movement for commander
5. Keep HQ width <= 8This is the formation cap
6. Minimize support to keep cost and command power lowCheapest single-player template is 2-width infantry

Use commander position and proximity correctly

Commander bonuses only apply to divisions directly under their command. Placing your commander close to the front line allows divisions to receive their full bonuses and planning efficiency.

If a commander is four tiles away from the front, they effectively do not supply bonuses. The proximity setting in the HQ panel (such as "close," "medium," etc.) does not override the physical placement of your commander. Only the location relative to the actual front line matters.

Sitting the commander directly on the front line entails no penalty — your divisions receive full planning. One tile away incurs a -5% maximum planning penalty and reduced ability efficiency. Two or more tiles back may give larger maluses. Practically, positioning commanders one or two tiles behind the line is safer, avoiding unnecessary risk while still delivering most bonuses.

1. Assign commander to Army HQ and front lineCommander bonuses only apply to assigned divisions
2. Place commander on the front line for full bonusesNo penalty at zero offset 9:22
3. Keep commander one tile back for safer positioning-5% max planning, reduced ability efficiency 10:04
4. Ignore HQ proximity setting if commander is directly on the linePhysical placement is what determines bonus effect 10:33
5. Regularly check commander tile for unexpected malusesRetreat commander from combat if needed

Choose the support staff that is actually worth using

Army HQs can fit a limited number of support staff, and for a first deployment two picks cover almost everything. Hospital Group Staff is the strongest all-round choice: extra division experience gain, reduced commander wounds and sickness, and 4% casualty trickleback with the "Stockpile Medical Supplies" decision. Logistics & Service Staff rivals it when supply consumption and command flexibility are crucial — it allows two more armies under your general and gives the Exploit Breakthroughs ability, which boosts plan retention and movement speed but increases damage taken. Reconnaissance Staff unlocks Defense in Depth, which provides max entrenchment for divisions in exchange for halved max planning and persists until manually disabled, and Signal & Intelligence Staff adds +3% max planning plus the Rotating Reserves ability. Signals, Recon and Maintenance are otherwise situational, useful only with specific needs.

Which company belongs in each slot, the full company list and the tier ranking behind these picks are covered on the companion page: HQ support companies: the best Army HQ setup.

Capture and free commanders

Army HQ commanders can be captured in combat through several methods: defeating their division in battle, surrounding and overrunning them in an encirclement, or reducing their strength or organization to zero before they have a chance to retreat.

When captured, commanders are instantly relocated to the nearest victory point (VP) of the capturing nation. For example, a German commander taken in the Netherlands may be moved to Utrecht, or if taken by a distant country, potentially to a far-off VP like Quebec. This means the real location of the battle may have little relationship to where the commander ends up.

There are several methods for freeing captured commanders:

• Conduct a raid on the province where the commander is held.
• Recapture the tile to liberate your commander directly.
• Wait for the end of the war; commanders are released automatically.
• Use transport planes and spies to attempt a rescue from a single location.

These mechanics encourage both offensive action and the use of intelligence agencies in a way not previously seen in HOI4. Rescuing via spies is especially useful for commanders held far from the front.
