Which DOD and Air Force forms are used when requesting an item that does not have a federal stock number assigned or when additional information is necessary for procurement?

The correct answer highlights the specific forms used within the Department of Defense (DOD) and the Air Force for requesting items that lack a federal stock number or require further information for procurement. AF Form 2005, known as the "Issue/Turn-In Request," allows for the requisitioning of items and is especially relevant when an item is not already cataloged with a federal stock number.

DD Form 1348-6, titled "Miscellaneous Transaction Report," is utilized when there is a need for procurement of items that are not standard, which often includes providing additional details necessary for processing. This form is crucial when specific item requirements are not standard and supplemental information is required to facilitate the purchase or acquisition process.

This combination of forms is the standard in these circumstances, which is why this option is correct. Other choices include forms that either do not pertain to procurement in the same way or are not the appropriate forms to use for items lacking a federal stock number.
