- Combat Chinook talking about the upgrade
The upgrade increases the cash flow of all these buildings by 10%.
- While this upgrade is shown to affect the USA supply center, it actually affects the Chinook itself. This can be observed when the player has another faction's supply building/collector. Supplies dropped by Chinese supply trucks/GLA workers at the USA supply center will stay the same, while supplies dropped by the Chinook at Chinese supply center/GLA Supply Stash would be increased.
