That's because no other military units are directly related to another type of military unit.
In fact you should actually be paying more for your tanks according my calculations if it was to increase by 0.01% per a tech level unless there is some factor that I missed.
Weird.
But then there is problem with all the military units not documented by how a WRC increases the cost.
It is basic knowledge what the WRC does, you should have read about it when you bought it.
You're living in the past, you can do 6 million 200 tech now.
You receive 6 million and then you send 200 tech in two separate transactions of 100 tech.
That more or less goes back to my first foreign aid transactions, great for me if it happens.

Wouldn't make much sense as they let their ally NG get attacked by Umbrella and didn't really respond, why would they attack Umbrella or TOP nations because of the NPO.
The problem is that interests are being placed above what is best for the coalition by those leading the coalition.
Though those are people deciding what is best for them, not necessarily the coalition.
