Defense Bonuses: How do they Work?

[Inverse Icarus]

i just realized i have no idea how it works.

say i have an infantry (defense of 10) on a mountain (+100%) in a fortress (+50%) with a radar tower in range (25%), but NOT fortified.

when a tank attacks the infantry, what is it's defense value?

do you add the %'s first? giving the infantry a 175% defense bonus, and a defense of 27.5 ?

or do they stack up? do you do the terrain first (def = 20) then the fort (def = 30) then the radar (def = 37.something).

i'm assuming the first, just want confirmation.

You add the bonuses first
