So you want to test new weapons? or conduct human psychology testing? Maybe you want to see well trained battle seasoned units against your own in staged assaults?
Testing on your own forces has its limitations - the best thing to test on is the real thing!
Test on the enemy...of course give them less lethal weapons but certainly arm your units with lethal weapons......or less lethal if you want to use the enemy over and over again!
But how do you get a live one?
Well the introduction of CPD TempX units has seen random, lone Mercs roaming the voids of Mallera-9 looking for kills of opportunity.
A skilful combat unit can find novel methods to capture them.
