Troops Upkeep: Troops * .11 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant 
Jets Upkeep: Jets * .14 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant 
Turrets Upkeep: Turrets * .18 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant

Spies Upkeep: Spies * 1 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant 

Constant = If MilBases/Land < .295 Constant = 1 - 1.3*(MilBases/Land) Else (that is, if the number of MilBases built is more than 29.5% of your land) Constant = 0.61</td>

<td>Alliance Costs</td>

<td>
Defensive Allies: DefAllies * Networth * .002 (0.2% of NW each) 
Offensive Allies: OffAllies * Networth * .002 (0.2% of NW each) 
Intelligence Allies: IntelAllies * Networth * .0015 (0.15% of NW each) 
Research Allies: ResAllies * Networth * .0015 (0.15% of NW each) 
Trade Pacts: TradePacts * Networth * .0005 (0.05% of NW each) 
GDI Costs (non-Theocracy): Land * 4 
GDI Costs (Theocracy): Land * 8 
Declare War Costs: Land * 10 

</td>
</tr>

<tr>
<td>GDI Penalty</td>

<td>Because of the defensive nature of the alliance, one side effect of GDI is 10% lower gains from your attacks.</td>
</tr>

<tr>
<td>Land Upkeep</td>

<td>
If land is less than 1500A: 
Land Upkeep = Land^2 * 7/1500 + Land*3 

If land is more than 1500A: 
Land Upkeep = Land * 10 

Note that when Land = 1500, both formulas give the same upkeep.
