Which item is categorized under FSC 23?

The correct categorization under Federal Supply Class (FSC) 23 is for ground effect vehicles. FSC 23 specifically encompasses items that are associated with air cushion vehicles, which are designed to travel over various surfaces while utilizing the principles of ground effect. These vehicles are unique in their ability to hover and maneuver with a certain level of efficiency, often used in various applications, including military and transportation sectors.

The other options fall under different categories; wood working machinery and equipment is classified under a different FSC that pertains to tools and machinery used in carpentry and woodworking processes. Similarly, rope, cable, and chains are categorized under an FSC related specifically to materials and lifting devices. Weapons have their own dedicated FSC focused on armaments and ordinance equipment, which does not include vehicles like the ground effect vehicles. Understanding these categories is crucial for logistics specialists to ensure accurate reporting and procurement of supplies.
