Units

Six of them. Three are infantry, trained at a Barracks and housed by your Barracks and Training Yards. The other three are vehicles, which are not trained at all — they are assembled out of the first three. For now every unit is used for one thing: carrying resources home from deposits.

Costs and requirements

Tables scroll sideways on a narrow screen.

Training time is per unit — a batch of five takes five times as long. Vehicles are priced in troops as well as resources; the full recipes are on the vehicles page.
Unit	Level	Made at	Costs	Time each
Infantry	1	Barracks	50 gold	30s
Scout	2	Barracks	50 gold	45s
Heavy Infantry	4	Barracks	50 gold	1m 30s
Recon Drone	3	Factory	4 Scouts + 150 gold · 75 materials · 40 energy, for two	1m
Light Tank	5	Factory	4 Infantry + 200 gold · 100 materials · 50 energy	3m
Battle Tank	7	Factory	4 Heavy Infantry + 400 gold · 200 materials · 100 energy	5m

All three infantry types cost exactly 50 gold and nothing else, which makes them the only troops you can raise from mine income alone. What separates them is training time and what they carry, not price.

Vehicles have their own page

They are housed in a different pool, cancelled on different terms, and can be taken back apart. None of that fits on a page about troops — see vehicles. Note also that although the Recon Drone unlocks at level 3, every vehicle is assembled at a Factory, and a Factory needs level 4.

Statistics

Speed sets the marching pace; carry is how much one unit brings home from a deposit. A vehicle's first four numbers are exactly the four troops it was made from, added up.
Unit	Health	Attack	Defence	Speed	Range	Carry
Infantry	100	15	5	2	1	50
Scout	60	10	3	5	1	25
Heavy Infantry	200	30	15	1	1	80
Recon Drone	120	20	6	7.5	5	50
Light Tank	400	60	20	3	2	200
Battle Tank	800	120	60	1.5	3	320

On combat statistics

Health, attack, defence and range are recorded for every unit and are raised by military research, but there is no battle system in the game yet — nothing attacks your base and you cannot attack anyone else's. Until that changes, the two numbers that matter are speed and carry.

Speed, in plain minutes

A party crosses one world tile in 30 seconds divided by its speed — and it moves at the pace of its slowest member, so one Heavy Infantry walking with a column of Light Tanks drags the whole party down to speed 1.

Outbound leg only. The walk home is slower when the party is loaded — see expeditions.
Speed	Units	Per tile	10 tiles out
7.5	Recon Drone	4s	40s
5	Scout	6s	1m
3	Light Tank	10s	1m 40s
2	Infantry	15s	2m 30s
1.5	Battle Tank	20s	3m 20s
1	Heavy Infantry	30s	5m

Which unit should I actually build?

Housing is the constraint, not gold — you will hit your Training Yard cap long before you run out of money. So the question is how much does one housing place carry, traded against how long the trip takes.

Carry per housed unit, against the marching pace that unit forces on the whole party. Vehicles occupy bays rather than bunks, which is why they are not simply better versions of the rows above them.
Unit	Carry per place	Per tile	Verdict
Battle Tank	320	20s	Best haul in the game. Needs level 7 and four Heavy Infantry apiece.
Light Tank	200	10s	The all-rounder, and the first conversion worth making.
Heavy Infantry	80	30s	Cheap bulk, but forces speed 1. Mostly Battle Tank feedstock.
Recon Drone	50	4s	Same load as an Infantry, at nearly four times the pace. Best on near deposits.
Infantry	50	15s	Available immediately, 50 gold, decent pace. Your whole early game.
Scout	25	6s	Half an Infantry's load for the same price. Build them to convert, not to send.

Rules of thumb

Never mix a slow unit into a fast party. One Heavy Infantry in a party of Light Tanks triples the travel time and adds 80 to the load.
Early game: Infantry, and lots of them. 50 gold, speed 2, carries 50. Nothing else is available and nothing else needs to be.
Once you have a Factory: convert. Four Infantry become one Light Tank that lifts the same 200 in one housing place at better than Infantry pace.
The Scout is only worth building in fours. Sent as-is it is the worst hauler in the game; converted, it makes the fastest.

Training and housing

The training panel on a phone: two capacity boxes at the top, one headed TRAINING SPACE with a Manage button and one headed VEHICLE BAYS noting that it is separate from troops, then the Infantry, Scout and Heavy Infantry rows, each with its cost, training time, a quantity stepper, a Train button and a MAX button. — The training panel. The two capacity boxes are separate on purpose — filling one does not stop you using the other. **Manage** opens the training space screen.

There are two housing pools and they never mix. Infantry go in training space — 5 per Barracks and 15 per Training Yard at level 1, doubling with each upgrade. Vehicles go in vehicle bays — 5 per Factory and 15 per Motor Pool. A full Training Yard does not stop you building a tank, and an empty Motor Pool does not let you train more infantry. See training space and vehicles.
Units in the queue count against the cap as soon as you order them, so you cannot queue past your limit and be surprised later.
One batch at a time, per building. A Barracks takes one order and then queues; the row says BUSY with the wait on it. Build the second Barracks the cap allows, or rent a Field Barracks Tent — the offer appears on the blocked row itself.
The MAX button never lies. Beside the quantity stepper it reads MAX 12, and that figure is already capped by what you can afford, what troops you have ready, and how much room is free in that unit's own pool. The largest single order is 99.
Ordering is refused before you pay. If you are over your housing cap or short on resources, the order is rejected and costs you nothing — the row tells you which, with NO ROOM, NO BAY, NO TROOPS or CAN'T AFFORD.
Cancelling a training order refunds half its cost. Cancelling a vehicle order does not — it returns the troops instead. See vehicles.
New units are housed in the facility that made them, and you can move them afterwards. See training space.
Units on an expedition still occupy their housing place and cannot be sent on a second run until they are home.
