How do supply lines work in Defilade?

A completed FOB connects to friendly lines by roads used by supply trucks. The trucks keep the FOB supplied; if the road is cut or the trucks are destroyed, the FOB is cut off.

Can I cut the enemy's supply lines?

Yes. Roads can be ambushed or cut, and the AI does the same to you.

What should I escort supply trucks with?

A cheap infantry squad or a light vehicle. Do not use your main army as an escort; keep it at the front and use a small guard for the road.

Do supply trucks cost manpower?

The exact economy is not published. The public material says supply trucks are the logistics layer that funds units and buildings.

Defilade Supply Lines Guide — Trucks, Roads, Ambushes and Cutting the Enemy

The supply chain

The confirmed chain is:

main line → road → supply truck → FOB → forward units

A completed FOB connects to friendly lines by roads used by supply trucks. If any link breaks, the FOB stops being supplied:

the road is cut;
the trucks are ambushed;
the FOB is captured.

The developer’s AI commander is built around this: it guards its supply trucks and raids yours. That is a direct hint that supply is the intended pressure point.

Defending your road

Guard the chokepoints — bridges, crossroads, the entrance to your base.
Use cheap units — a single infantry squad or a watchtower is enough to make a raid costly.
Mine the road — mines and wire slow a raiding party.
Keep a reaction force — a small mobile squad that can respond to a raid.
Do not over-escort — if your main army sits on the road, the front collapses.

Attacking the enemy road

Find the road between the enemy FOB and their main line.
Cut it with a small, fast force rather than a frontal assault.
Ambush the trucks — the developer explicitly lists rebel ambushes as a full-build feature.
Attack when the enemy army is committed at the front; the road is weakest then.
Do not overstay — a raid that kills one truck and escapes is better than a raid that trades the whole squad.

Supply and the FOB

The FOB is the forward end of the chain. A FOB without supply:

cannot resupply troops;
cannot sustain the unit cap it provides;
becomes a trap if the enemy attacks it.

That is why the FOB guide says: place it on a road, defend the road, and do not build a second FOB before the first is connected.

Supply and the economy

The public material describes supply trucks as the logistics layer that funds units and buildings. The exact numbers are not published. What is clear:

manpower is finite, so capture points matter;
supply trucks are a physical unit on a physical road;
losing trucks hurts the economy, not just the front.

This is the part of Defilade that most resembles Company of Heroes: the fight is not only at the front, it is on the road behind it.

A simple supply checklist

Every FOB is on a road
Every road has a guard
Every guard has a reaction force
Every chokepoint has a mine or a wire
The enemy road is scouted before you attack
The raid force is small and fast, not the main army

We will add truck counts, supply rates and road-build rules after the December 1 demo.
