Nah, for a bunch of people caught out in the open...
cluster bombs like the CBU-75 or the CBU-58 are better solutions. The Daisy Cutter can also kill people caught out in the open but cluster bombs work better.
For those who don't understand cluster bombs, think of them as a grenade dispensor. The CBU-58 carries the equivalent of 650 grenades (called bomblets) and is very effective against personnel and light vehicles.
