target area

Time On Target

Time on target or (TOT) is an estimate of when an artillery bombardment or an airstrike will strike an intended target area. It was first developed by the US Army shortly before World War II to help improve the effectiveness of artilery firepower.

Allied artillery units were often trained to fire their guns in a precise order, so that all shells would hit a target at the same time, delivering the maximum possible damage. This is given to the soldier or officer who requests a bombardment or an air strike.

A shorter TOT usually means a smaller or less important target, and the deployment of less artillery or aircraft. A longer TOT means that the target is large or extremely important, so preparations for a massive bombardment or air strike will take longer.
