BEHIND <number> time: 0 days priority: 1

Indicate how close to the front lines the unit should stand in combat. Number should be between 0 and 9. 0 is the front, 9 the rear.

Only missile fighters such as archers may attack from the rear. Swordsmen, knights, etc. may not. When all of the units in a row have been killed or taken prisoner, the next row will advance (skipping any empty rows).
