And another one found on War Is Boring, the US M25 repeater rocket launcher.
However, being about three times heavier than the M20 Bazooka, it needed a tripod mount and at a time when it really needed a more capable warhead to counter the more heavily armoured Soviet tanks then being fielded, it fired the same round as the M20. So naturally enough, the US Army declined the weapon.
