There are some threads on this.
What you must understand is that the cost of the weapon must be included with the cost of the soldier.
You will find then, that a SS with the best gun costs only 150% that of a Merc and the best gun.
However, the SS is 200% more effective.
I.e.
Here are the costs:
156,000+91,000 = 247,000 SS
156,000+3500 = 159,500 Merc
156,000+2000 =158,000 TU
Damage (Based on replicators):
1X2560X2.5575X1X10 = 65,472 SS
1X2560X2.5575X1X5 = 32,736 Mercs
1X2560X2.5575X1X5 = 32,736 TU (may actualy be a little less i'm not sure)
As you can see SS do twice the damage, for under twice the cost.
One final example:
For every million in defensive power (for reps) It will cost about 3.8 million worth of SS and weapons.
HOwever, for every million power in Mercs it will cost around 4.8 million.
I.e. After 100million Def power worth of SS you will have saved 100 million naq AND be doing more damage than if you had gone with mercs/ut.
I make no guarantees about the acuracy of my math.
