Use the Category, Branch, and Era filters to focus on specific families. The Branch filter (Army · USMC · Navy · USAF · SOF) surfaces service-unique weapons. The ⬡ Lend-Lease / Export filter highlights the 35 weapons with significant foreign military sales or Lend-Lease history — including weapons whose export story is rarely told: the M1911 in Norwegian service, the Thompson SMG with the British Expeditionary Force before Pearl Harbor, the M1 Bazooka reverse-engineered by Germany into the Panzerschreck within months of capture, and the M4 Sherman's 17,000-unit British Lend-Lease run.
