The Alliance's participation in Solaria's war is certainly not free of charge.
The Executive Council needs to contribute financially, the Star Realm Army Headquarters also needs to fund it, and the Military Affairs Department must allocate funds as well.
Within the Alliance Army itself, there exists a Star Realm Army unit from the Rage Bear Legion. This unit can be utilized at this time.
Since they are participating in the war as part of the Star Realm Army, they must receive all the standard benefits that come with being in the Star Realm Army.
Costs for replenishing various equipment losses and budget allocations for the entire legion are all required.
Moreover, the prices for the Alliance must be even higher.
