And not paying for their upgrading, and in many cases, not even their food and fuel. Seems like a bargain to me. Of course, the trick is getting the right countries and putting their INF in the right places to maximize the most while best using their different attributes and weaknesses. Should also mention that some of these countries have units this UK does not even yet possess - especially MTN and CAV.
Isn't all this diplomacy rather expensive? Still, you need some weak INF to suppress partisans in all this territory you are about to acquire.
Actually, as regards partisans, UK is much better building a line of GAR - less IC, faster, less supplies consumed, and much better results.
As regards the "cost of diplomacy" UK's costs are relatively cheap. But importantly, it is all being mostly funded by getting rid of vast amounts of surplus resources. You also get back a fair amount of money and resources once you give these countries the many advanced plans you possess. And occassionally some of them will give you a plan quite advanced past your own research. Finally, as regards playing, it does sort of add another dimension - perfect for any "micromanagement fanatic."
Isn't all this diplomacy rather cheap? You only pay about 2400 $ or 1000 icd and get something like 20 Inf without having to pay manpower for it.
Actually average cost per country is only about 12 influences (as some are big influence) plus "invite". Given next slider move coming soon, that would be only $1120. But as some other coutries turn out to be "failures" and the higher earlier costs, Pang's estimate is also a good one.
