The most time-saving feature of Overthrow is the AI 'loot' command. Any violent revolutionary is going to end up with a lot of... stuff to pick up, so one of the earliest tasks should be acquiring enough money to recruit a civilian and assign them to battlefield detail.
- Hire a civilian using the 'Y' menu while close to one and selecting "Talk"
- When in your group, press F2 to select your new civ
- Move them next to a vehicle or ammobox by middle clicking on the map or in your view
- When standing next to the container, select them with F2 again
- Press 'Y' with the unit selected
- Click on "loot"
The unit will start to loot into the nearest container, any bodies within 200m
