While battlefield recovery was probably a thing long before Hannibal was a Private, I thought of what I'd first read 40 years ago about North Africa - where both Germans and the Commonwealth wreckers would haunt battlefields after dark vacuuming up anything the could be reused/recycled/put back in the line.
This was considered diametric heresy from what was US Army policy in the late 20th/early 21st century, in that "
cannibalization will not be tolerated".
*Uh huh*, said a skeptical I back then.
Just now, I wondered what was the reality.
This from Tunsia, April 1943 (and probably with some guidance from the Commonwealth's Desert Rats) -
"During the El Guettar-Maknassy operations Colonel Medaris began to use a new type of company that he put together from men and equipment of the 188th Battalion calling it the Provisional Ordnance Collecting Company. Its job was to go into the forward area, whether the actual field of battle or ground over which combat troops had merely passed, and bring back all the Ordnance matériel it could find, Allied or enemy.
This was a pioneer effort at battlefield recovery and evacuation. An Ordnance evacuation company (TOE 9- 187) had been organized in the United States in November 1942 but it had not yet arrived in the theater; besides, it was mainly for evacuating armor from collecting points to the rear, being equipped with tank transporters rather than wreckers and trucks. Theoretically, combat troops cleaned up the battlefield, bringing damaged matériel to division or corps collecting points where Quartermaster troops picked it up, sent it back to depots, and if it was repairable turned it over to the technical service that had supplied it.47 Experience in Tunisia showed that the combat troops did not have the time, manpower, or equipment to clear the battlefield. It took 4-ton and 10-ton wreckers, plenty of 2½-ton trucks, and men with special skills—riggers, tank mechanics, welders, and drivers who could handle tank transporters and other special vehicles. To get these, Medaris robbed the maintenance companies of his 188th Battalion, pooling all evacuation and recovery equipment in his collecting company. This was hard on the maintenance companies, but the collecting company recovered a tremendous amount of supplies that might otherwise have been lost, and many of the items were promptly returned to service. On one occasion the equipment of an entire battery of 90-mm. guns, badly shot up by enemy artillery, was collected between 1700 of one day and 0600 the next, and taken to an Ordnance maintenance company, which repaired it and got it ready for action by 1600 of the following day."
