The 15,000 pound BLU-82B bomb was a system used during the Vietnam war. Nicknamed the “Daisy Cutter” because of the pattern it made when clearing jungle. Dropped from a C130, the bomb had a rod that detonated it a few yards from the ground.
The Command Vault project was used by SOG a few times to clear new landing zones for recon teams in Laos. The result was reported to be impressive.
