Def--
Front row, both sides are MK-82 GP 500Lb bomb, with standard MAU-93 fin for "slick" configuration.
Second row, both sides are M-117 GP 750Lb bomb with MAU-91 fin for "slick" configuration.
third row, inside, MK-84 GP 2000Lb bomb with slick fin, I think a MAU-103.
Third row outside, Those are CBU's, I cant really tell the type in that picture, but prolly CBU-52 or CBU-58. If its a newer model it could be a "gator" whic is a CBU-89. Could also be CBU-87. All these weapons have different bomblets and are used in different rolls, varying in degrees of anti-personnel and anti-armor rolls.
