MOAB is a surface blast effect weapon with a wide diameter kill range, MOP is a subsurface bunker buster with a narrow diameter killrange.
Not at all the same thing. The MOAB cannot “do” MOP targets, all the Nuke plant targets in Iran are MOP targets.
The MOP cannot do area effect MOAB targets, they are taliban strong holds in Afganistan.
NOT being redundant at all, deep is not the same as wide.
