Read positions

Only the radio unit can read positions, that means it gets all sights of every section's unit within range. Units too far away from the radio won't give their sights to the radio. For the next 3 days, these sights will appear in the map, except where an active unit has a sight (which is more recent than the reading). This reading can be shared by all sections of the army, others radios can use the "check other reading" action to get your reading.
If you want to know the date of a reading on a cell, let the mouse a while on it, the date will appear soon.
You can't read positions on an enemy occupied cell.

Weather affects range of reception of the radio.
