Which weapon is described as not being a standalone weapon system due to its multi-barrel design?

• A. GAU-2/c
• B. GAU-18A
• C. GAU-21
• D. M134

Answer: (A)

Rotary multi-barrel guns rely on an external drive and feeds to operate. Their rotating barrels need power, mounting, and ammunition handling as part of a larger gun system, so they aren’t used as simple handheld or standalone weapons. The GAU-2/c is a 7.62 mm Gatling-type gun used on aircraft and helicopters, designed to be mounted with its power, feed, and control systems as a complete gun system. That design characteristic—the need for an integrated gun system due to the multi-barrel arrangement—fits the description of “not being a standalone weapon system.” The other models are configured differently within their platforms, but the key point here is the multi-barrel rotary design that requires a broader gun system, which the GAU-2/c exemplifies.
