Resource fields and supply convoys
Your army can build an economy as well as win battles. Send a supply convoy to a green resource field for predictable material income, without combat or a purchase.

Choose a field and a schedule
Open the World Map, select a green resource field and choose Send supply convoy. A field shows its resource and hourly yield. Choose 15, 30 or 60 minutes of extraction, then assign transport troops. Travel to the field and the return journey are added to that duration.
Transport is a strategic choice
Each unit has a carrying capacity. Your convoy brings home at most the smaller of its total carrying capacity and the field's output for your chosen extraction time. Infantry can carry cargo, while Scout Cars travel faster and carry more per unit. Mixed convoys travel at the speed of their slowest unit. Officer march-speed bonuses apply to combat and scouting, not supply convoys.
One army, three deployments
Supply convoys, scouts and attack marches share the same three active march slots. You can send one convoy per field at a time. Assigned troops are unavailable for home defense, training is unaffected, and your shield stays active. Supply convoys have no combat casualties. Fields are renewable: different commanders collect independently.
Cargo is delivered on return
Extraction finishes before the return journey. Troops and cargo become available together after the convoy reaches home, including while you are offline. The supply log shows what was actually delivered. Keep storage space available: cargo beyond your resource cap is lost. You may recall before extraction finishes, but an early recall forfeits the cargo.
Balance safe income with the campaign
Use convoys to fund replacement troops and upgrades while preparing for NPC battles. Gathering does not count as a battle victory and does not grant rank points or War Bonds. Campaign and combat rewards remain separate, so choose which activity deserves each deployment slot.
Your first orders are waiting.
