I couodnt fail with penals since there is no automatch. I only tested units vs ai to see they are same as substance inside your head.
If you would listen to miragefla last stream and in every focking post he did about penals, you would understand that penals arent very tanky. They wont withstand much dmg, but this isnt their job. It is scheduled that you play them in combine with conscripts! Conscripts as meatshield and Penals on long range as dps dealer.
I know Combined arms isnt easy for everyone.
