How’s Your Sherman, Herman?

M4 Sherman Tank modification and upgrades from Army Motors, Maintenance Branch, Office of Chief of Ordnance, Vol. 5, No. 1, April 1944:

If it’s a Tank, Medium, M4—here are the visible changes that should have been made by now. Check your score—and chase whatever’s missing.

How is Your Sherman, Herman - U.S. Army M4 Tank Modifications and Upgrades

Sorry our list couldn’t quite Tell All. For details on the above additions, subtractions, and modifications, you’ll have to consult the TB’s and FSMWO’s themselves. There are plenty of other TB’s you should have seen, too—full of fascinating facts on M4 operation, identification, lubrication, adjustments, cautions, and assorted SOP’s.

You’ll find all these cataloged in the latest edition of OFSB 1-1, under “pertinent publications” for the Tank, Medium, M4. Anything else is impertinent, including that remark you just made about having so much to read.
