query: What was the reason for the PVA's use of captured US weapons during the First Phase Campaign in the Korean War?
answer: During the First Phase Campaign (October-November 1950), the PVA used large quantities of captured US weapons because the required ammunition was readily available, and resupply across the Yalu River was increasingly difficult due to UN air interdiction operations.
