T20 lite does not address this (or if it does I haven't noticed), so I can only guess at it until the full T20 is in my grubby little hands. So, my guess is that these rounds ignore the first 5 levels of armor for hit and damage reduction purposes. Although I'd probably restrict this to actually defeating the armor (-5 dr).
