Actually. I was wrong.
The game has a Sensors mode. This allows you to explore a large 3D view of the entire map. Everything is colorcoded. Red = Enemies, Yellow = Allies, and Green = You.
When you move a unit, you click on it then right click. A large blue circle will appear. It will resize itself as you move the mouse around. Around the cursor, is a smaller yellow circle. This is where you want the unit to go.
As you go farther out, the distance from the selected unit and your mouse cursor increases. It first starts out as Meters, then eventually gets to Kilometers.
A KM in this game is quite far as it is, so, my statement of the Trinity Cannon having a range of 6000 Kilometers is a massive loving exaggeration. It's actually 6000 Meters.
Also, where's loving Gadge with the damn projectile?
