I am not sure what that bomb is but in the filenames are the letters jdam but JDAM isnt really a bomb. As far as I am aware, it is a tail kit that
makes ordinary bombs into smart bombs.
Since the URL contains the identifier jdam_wsep and jdam_bda, one could conclude these is a videos of the Joint Direct Attack Munition Weapon System
Evaluation Program, and Joint Direct Attack Munition Bomb Damage Assessment respectively.
