For 75 years, this story has been untold. 324 pages with over 200 never-before released photos of captured enemy equipment
being readied for shipment from Depot O-644 Paris, France, for evaluation at Aberdeen Proving Grounds during WWII. Many
of the tanks, cannons, railway guns and V-2 Rockets do not exist anymore past these photos.
Several of these tanks and artillery pieces, shown in this book, were on display in the later 20th century at the Aberdeen,
Maryland Ordnance Museum and are now at the Fort Lee Museum, Virginia.
Master Sergeant Paul Cernak, Non-Commissioned Officer in Charge (NCOIC) of the 265th Ordnance Service Company, under
the command of Major Stone and General Saylor, was responsible for processing all of this captured foreign intelligence
equipment for shipment to England and the United States in 1944 through the closing days of WWII, to include Operation
BACKFIRE, the reverse engineering of the German V-2 Rocket Program.

Ordnance Technical Intelligence Teams were responsible for the capturing, identification and shipment of foreign intelligence
equipment for shipment to the United States. Early in the WWII, the U. S. Army saw the necessity for immediate first-hand
technical observation, and in December 1942 the first Ordnance Intelligence Team: several specially-trained Officers and
Enlisted Men, were dispatched into combat. Their mission was to procure enemy weapons and ship them to the United States
to be used in a continuous study of the latest developments and trends in the enemy armament industry and to rapidly
develop counter weapons. By the end of WWII, very small teams of highly trained technical observers and collectors were
working in every theater of operations to obtain enemy material for evaluation.

This book also covers the pre-Normandy invasion work that was done by these Ordnance Personnel prior to June 6th 1944.
Their efforts resulted in the testing and successful waterproofing vehicle tests conducted in England between 1943 and 1944,
for issue of the Asbestos Waterproofing Compound (AWC) used to waterproof all Allied vehicles for Operation Overlord.
Multiple previously classified never-before seen photos are present in this book of the testing being done in England.
After the Normandy Invasion, these Ordnance Men headed to mainland Europe to collect, process and ship the advanced
enemy equipment, shown in this book.
