Here's an idea for putting fire on something/someone
Use a basic coordinate system, and equip the arty with better maps. Say you could punch up the entire grid square F4 is in. From that, you'd have the usual number coordinate system to direct fire from.
E.G.(over RW): "Steel rain, Hotel 4. Gimme one round Willy Pete at X-ray 871904, Yankee 113617. Round fired on-call, over"
Or something to that effect. Just imagine planes trying to fly
under the arty trying to cap a field! Now wouldn't that get your blood pumping!

"Therefore; if able, appear unable, if active, appear not active, if near, appear far, if far, appear near. If they have advantage, entice them; if they are confused, take them, if they are substantial, prepare for them, if they are strong, avoid them, if they are angry, disturb them, if they are humble, make them haughty, if they are relaxed, toil them, if they are united, separate them."
