00:00The Lazy Dog was a short steel rod, dropped from aircraft in bulk, carried no fuse and no explosive.
00:06All the damage came from height and speed.
00:08A rod released from altitude keeps accelerating until drag balances gravity,
00:13and the fins or shaped body hold it nose first when it falls.
00:16Nothing about it was clever, which was the point.
00:19I changed one claim from your original.
00:21Precise doesn't fit the history.
00:23These were dropped in large numbers over an area,
00:26and individual rods landed wherever wind and release height set them.
00:30The USAF used them in Korea and Vietnam,
00:33and they were considered a crude weapon more than a surgical one.
