Priority Hexes are pre-plotted artillery fire locations.

Normally to get an artillery mission a forward observer has to radio in to a Fire Direction Center who then determines which artillery assets are available and calls them and passes on the fire mission. The artillery battery then has to calculate the direction and distance to fire to hit the desired location and get the guns moved.

With a pre-plotted (i.e. priority hex) the firing battery already knows the direction and distence because it was already calculated. And it's quite possible the guns are already pointed where they need to be.

Thus the response time between the call for, and the arrival of a fire mission is reduced.

Hope this answers your question.
