Just dug up something interesting from tanknet.
http://www.globalsecurity.org/milita...t/1990/TJD.htm
Under "General Threat Overview", it saids in fire tests conducted in 1988, 105mm DU rounds could not penetrate T-72 export model but exact details are not given.
Does this mean frontal arc of Iraqi T-72s are immune to M60 Pattons' 105mm guns?
Does anybody know the details of this test?
