Just a quick note about how ignorant our Commander in Chief is of the US military. He apparently expects to display "brand new Sherman tanks" during the July 4th festivities in DC.
Sorry to disabuse you Mr President, but the last "brand new Sherman tank" was built about 2 months before you were conceived to your father, who somehow avoided serving in the war for which they were built.
They were also taken out of service in 1957, about 11 years before you fabricated bone spurs to avoid service during the Vietnam War.
