You may joke, aviation wise why do you think we had practice thousand pound bombs painted blue, they were full of concrete and could be dropped and recovered, a new tail fin fitted and used again.
I seem to remember they were also used later in smaller sizes for dropping buildings on top of the bad guys
Lots dropped in anger in GWI.
Iraqis positioned their aircraft*, tanks etc around mosques, hospitals, schools etc so they’d be safe from attack because of the collateral damage.
A practice bomb with an LGB kit proved more than effective at totally destroying a tank or aircraft etc without damaging the building alongside.
*They towed the aircraft off the airfield and towed it back before a sortie.

A problem which also led to the development of the SDB and the R9X.
