Which block in NAVSUP Form 1250 contains information about the item description?

The correct choice identifies Block 3 as containing the item description on the NAVSUP Form 1250. This block is specifically designated for detailed information that describes the item being requisitioned, which includes essential characteristics and specifications necessary for identification and processing.

Understanding the organization of the NAVSUP Form 1250 is critical for ensuring accurate communications and documentation within supply operations. Each block serves a distinct purpose, facilitating the flow of information regarding supply requisitions. In contrast, other blocks, such as Block 1, Block 2, and Block 5, serve different functions such as indicating requisitioning office details, the requisition number, or other administrative information, which do not pertain to the actual description of the item. Thus, recognizing that Block 3 is the correct source for item description is essential for effective use of this form in a supply chain context.
