How can I accurately determine line of sight for a unit in Frozen Synapse?

Knowing the area visible to a unit and the area from which that unit is visible seems to be an essential part of the game. The aim command shows a cone of possible coverage but that doesn't reflect what is actually visible to the unit.

Is there any way to determine what areas on the map are visible to a unit other than eye-balling it?


Solution 1:

Use the hotkey 'v'. Click on your unit, or even on one of his future waypoints, and hold the v key. Move the mouse around, and you can see what his line of site is like, what he can shoot past, when he'll hit a wall, etc.
