Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "_reinforcementDefination.lua" file in the "\assets\world\[map name]\scripts" directory in the game folder. Locate the text similar to the following:

------------- litachki ----------------- aircraft = {} lastaircraft = {} ---------------SLOJNOSTI if difficulty == hard then
TankReinfTime = 300
InfReinfTime = 240
ArtilleryDifTime = 180
AirCraftDifTime = 300
end
if difficulty == normal then
TankReinfTime = 240
InfReinfTime = 180
ArtilleryDifTime = 120
AirCraftDifTime = 240
end
if difficulty == easy then
TankReinfTime = 180
InfReinfTime = 120
ArtilleryDifTime = 60
AirCraftDifTime = 180
end
end

Edit the "Time" values, which equal the amount of time in seconds required for recharge.
