:::Jack, you're welcome.  If you have solid information on the real capability of the M433 to penetrate reinforced concrete, pray let us know.  What is in the table is my estimate based on the ability of the round to penetrate 5cm of RHA.  As far as the "limited service" phrase goes, I'd be happy with it stating "test and evaluation" instead.  I wonder if L-3 still has the program in cold storage.  Cheers,
