Proposed Canon
Upkeep is the amount of money paid by a side every Turn to retain the services of a Unit and cause its rations to pop.Erf-b1-p039 and Erf-b1-p138 Upkeep is paid every turn, but does not need to be paid in full. By consuming provisions, only a portion of a Unit's upkeep needs to be paid. If the necessary portion of a Unit's upkeep is not paid, then the Unit will disband.
Field units have higher upkeep than Garrison units.
 Upkeep Examples
- Parson Gotti -- over one thousand ShmuckersErf-b1-p039
- Increased by 140 Shmuckers when he promoted himself to a Field Unit
- Archons -- from 200 to 500 Shmuckers
- Decrypted Ansom -- zeroErf-b1-p145.
The figures above seem to be the two extremes: Stanley is disgusted that even a Chief Warlord could cost over 1000 per turn (suggesting it is one of the highest he has encountered), and Parson seems shocked that Decrypted Ansom would have no upkeep at all. It is quite possible that the upkeep for uncroaked and other low-level units might cost 0 or near 0 schmuckers.
It is not known if any upkeep goes to the Unit itself (as a wage), or if it all simply disappears.
When Queen Jillian razed Progrock, she notes the 40,000 schmuckers it generates was enough to pay the upkeep for her entire side for 8-10 turns. This makes Parson's 1000+ upkeep/turn seem truly enormous.
