indeed redeye, leaving asid where they got the statistics from a guy I once talked to said to me that "the best tactic when leading conscripts is to run away before they do"...generally people will fight better if they're professionals who see soldiering more as a job than some matter of national pride (though that does creep in I suppose, but take my example-a mick who has no qualms about fighting for the "great oppressors of my nation"

because I view soldiering as a job). Its easy to go flag waving but when the s**t hits the fan you might be more likely to say "ah f**k the queen, you won't see her out here until the mass burials...".
Conscripts throughout history have generally fared off worse when compared to professional soldiers-even during WW1+2 if you were to take for instance the volunteers from neutral nations such as the USA during most of WW1, or Ireland during WW2 then you'd find that they would fight better than conscripted lads. I think we can all agree that for one reason or another small professional armies tend to fare better than even the largest conscript armies and chances are part of this is the willingness to kill.
As for those we would generally class as "sick minded" in civilian life, well perhaps they're just the sort you need in the military-the idea of armies, wars and having a shiney SA-80 in your hands is to commit what is viewed in civilian life as the greatest of henious acts, and not only do you get to shoot shell and bomb the feckers but at times you get to do it with your bare hands-surely thats not something you wanna train half your population over 18 to do.
