The JDAM precision is 5m. More than 30 years ago: https://en.wikipedia.org/wiki/Amiriyah_shelter_bombing https://en.wikipedia.org/wiki/Amiriyah_shelter_bombing "At 04:30 on the morning of 13 February, two F-117 stealth bombers each dropped a 910 kilograms (2,000 lb) GBU-27 laser-guided bomb on the shelter. The first bomb cut through 3 metres (10 ft) of reinforced concrete before a time-delayed fuse exploded. Minutes later, the second bomb followed the path cut by the first bomb."
