Here is a video of the M-69 Bomb. TOTALLY INEFFECTIVE ON IWO!!!!!
Remember the article a few days back about how EVERY major Japanese city had block wide firebreaks. Not effective there either.

ok, may have to eat my words. Lemay and the M-69 and low level bombing may have arrived as a team. But WHY were the general purpose bombs so ineffective?

The high altitude bombing attacks using general purpose bombs were observed to be ineffective by USAAF leaders. Changing tactics to increase the damage, Curtis LeMay ordered the bombers to drop incendiary bombs to burn Japan’s vulnerable wood-and-paper buildings.[7] The first such raid was against Kobe on 4 February 1945.
