Rotating troops at the front of battle

[Legosoldier]

I don't rotate units. It's hard to do and it causes extra casualties. what I do is just keep the formation and engage only to reinforce a unit without withdrawing, unless it I'm reinforcing a skirmisher or missile unit.

Thank you LorDBula I'd forgotten Alt retreats facing the enemy!

[Tartaros]

i must use this in wall-fightings and only if needed in battles.
i think its very difficult. sometime, if the units are exhausted or have a low moral they try to rout for real. this manoeuvre also cause a little bit more panik, because the other unit don´t like to see comrades rout. a deal with the fire...

[Tollheit]

Sparingly.
When I do it, first I order the replacement to attack, then I give the formerly engaged unit the "hold formation" and "stop" orders, and instead of actively retreating the unit I simply wait for it to drop out of combat.

I do this frequently, taking extra casualties into account. Fresh units are fighting better while the exhausted enemy is more likely to rout. The unit that just been pulled can recover behind the front line and join in again as fresh unit.

[Che Roriniho]

I usually do, by flanking the opposing unit with my back-up troops, then withdrawing my tired troops.

Thanks also for reminding me about alt-move.

as romani, all the time; usually though, my attacks are so furious, that the enemy routs before I need the second line

no discipline with the enemy..especially with a horns and breast style attack (of a cattle-its a zulu way of attacking)
