The federal definition of MI for PASRR is best understood in terms of the four âDâsâ: 1  A diagnosis or suspicion of a major mental illness such as schizophrenia, bipolar disorder, major depression, or an anxiety disorder such as OCD. 2  An absence of dementia. 3  A well-defined duration.  A particular level of disability.
Well-known World War II tanks were the German Panzer IV, Panther and Tigers, Soviet T-34 (produced in the largest numbers of any tank of the war and second most ever), British Matilda, Churchill and Cromwell, and American M4 Sherman (second most produced tank of the war) and Stuart tanks.
The British had most of the tanks on D-Day; a new American tank designed to float in to shore like a motorboat hadn't worked out. Most of them sank. But right behind the British beaches were the suburbs of Caen, a dense Norman city of sturdy stone houses that might have been deliberately designed to frustrate tank men.
