Allies support is the interaction of two players within the same union which involves transferring fleets to each other for temporary use.
Allies support lasts for exactly 6 hours and then the fleet returns to the owner.
The support fleet does not require energy to be sent to an ally, but when attacking, the support, like any other fleet, must be fueled (2% of the cost of ships in energy).
In this mode, the entire fleet is used as a combat fleet and cannot perform special functions (cargo transportation by Hercules or scouting by Loki)
