Spotting Charge
A signal (spotting) charge is normally used in practice bombs to give a visual indication of point of impact by releasing a puff of smoke.

UXO (Unexploded ordnance)
Military munitions that:

• have been primed, fused, armed, or otherwise prepared for action;
• have been fired, dropped, launched, projected, or placed in such a manner as to constitute a hazard to operations, installations, personnel, or material; and
