What brevity term refers to no ordnance remaining?

The term "Winchester" is used in military communications to indicate that there is no ordnance remaining. This term is derived from the Winchester Repeating Arms Company, which is known for creating firearms that allow repeated firing without reloading. When a unit reports "Winchester," it clearly communicates that they have exhausted their ammunition and are no longer in a position to continue fire operations.

Understanding this brevity term is crucial for effective communication in military operations, as it informs commanders and support teams of the operational capabilities and limitations of their forces. This enables timely and appropriate responses to ensure unit readiness and adjust tactics as necessary based on available resources.
