I'm about to start playing for the first time and would appreciate if someone could expand a little on the difference between Veteran Guardsmen and Kasrkin. Another player will almost certainly end up playing Death Korps, so I wouldn't mind trying something different for the sake of variety but I am just baffled by the number of warbands and kill team editions that are involved. While I would prefer something Imperial Guard related I am happy to play any human warband that is not too difficult.
Thanks.
