Time on Target: This indicates the delay before the barrage or aircraft arrives. The delay
length is the number of turns it takes the artillery to get a fix on the target, fire the shells, and
for the shells to strike. For example, a 0 means the unit can fire at the end of the current turn,
and a 1 means the unit cannot fire until the end of the next turn and so on. A barrage arrives
in the vicinity of the target at the end of your turn, from 0 to several turns later, depending on
the type of Indirect Fire requested and quality of the crew in question. Frequently, the arrival
time is expressed as a number plus some decimal fraction, for example, 1.3. This means that
the Indirect Fire is going to arrive over two turns, with three quarters arriving one phase and
the other quarter arriving in the next. A delay of 0.2 or less will arrive in the current turn, 0.3to
.5 will fall in the next and 1.0 or higher a whole turn (two fire phases) later.
You can change the arrival time of the initial bombardment or
airstrike by canceling the fire mission and then typing the
letter “T” to change the ETA. A popup box will ask for turn to
enter or fire. Type this in and reassign the fire mission.
