Reason #27 for America to offer weapons to Ukraine to defend itself against the Russians, the USA gets to see modern warefare and how our expensive weapons actually function on the battlefield. Case in point, Ukrainian forces are withdrawing US-provided $10 million per Abrams M1A1 Main Battle Tanks from the front lines after at least five have been destroyed by cheap Russian drone swarms. Without complete air superiority, today's modern tanks are just slow, big targets for cheap drones. Thanks to Ukraine's brave soldiers for saving American lives and money for future conflicts.
