However, I was speaking somewhat more narrowly of active defensive combat situations. I think this is pretty different from the peacetime conscription practiced by Finland, Sweden, etc. I was speaking of the group that did not volunteer when given impetus to do so.
Let's say that Finland were invaded by Russia. First, the currently-conscripted Finnish army would defend. Secondly, any additional volunteers from the populace that would like to help defend their homeland, will also help defend. Thirdly, if these first two groups are insufficient, additional conscription will be performed against the remaining population.
My claim is that on average, the third group will perform more poorly than the second group. I don't mean to compare either to the first group.
