Thanks Grutch, I've been meaning to write up this article for a while now, but haven't found the time...
I'll be happy to re-work the article for the War Room as you require, just let me know what you want me to do.
In response to the statement about being charged by 2 enemies... well it is really no different.
* The main thing to remember is that you'll flee from the largest unit strength, so make sure that the archers are in the right position to flee at an angle from this unit that will force both units to hit the parent unit only!
* Also if the enemy cannot physically reach a unit because another was moved first in the charge order, then they will fail their charge! This means that it is possible to align the archers to the first unit moved in such a way that the second unit cannot touch them! You have to be sneaky, but it's possible in some situations. This could allow you to hold against one charge while the other fails, then you can accept the overrun/persuit move into the parent and send the detachment into the flank on your next charge... the second unit that charged you would have failed its charge and will most likely not be in the way.
* The best way to prevent multiple unit from charging one unit is to have lots of infantry blocks... this forces them to divide up their strength among many of your strong CR-generating infantry units! I run an army with 4 units of 30 swordsmen each with a detachment of 10 swordsmen and a detachment of 5 archers plus 2 units of cavalry and 4 artillery pieces... this means that some enemy units will be killed from artillery and are not a threat, helping to thin out the lines, then the remainign units are spread out a bit and find themselves forced to try and arrange themselves for a duel charge, that might get them charged if they are not careful or simply split up and fight individual units.
* Panic tests also help, if you move soem units farther forward or backwards so that the enemy doesn't engage your whole battle line at once, you can break a single unit and it can have a good chance of causing panic on others nearby... thus removing the nasty business of actually fighting the enemy! Personally this is my favorite mothod of killing the enemy: Brutalizing the first wave of attackers so bad they run screamign for the hills and pasnic their buddies behind them... forcing a route and an easy run down as my units chase the scattered forces off the field. Most of my games go this way when I keep a strong battle line, I can break multiple units and remove any coherancy the enemy once had making it easy to chase them away... I often find myself in their deployment zone with most of my army by the end of the game even though I usually stay still after the first 8" or 12" I gofordard to set up my battle line.
* Also it is possible to place two units right next to each other, when an enemy with a wide frontage hits one unit they usually will overlap a little clipping the second unit, plus their buddies that charged in will also hit this unit makign one big combat. Both flanks will slam shut as the detachments charge in and it becomes a deathtrap for the enemy. However this is not the least bit safe to do if the enemy charging in is a high kill enemy unit... if they charge in with multiple high kill units then teh extra kills will easily negate the multiple units on our side as only one unit actually generates CR on my side,while the enemy's unit all generate CR. So don't let 2 units of kngihts charge into two units of infantry and link them together into one combat or the enemy will simply have double the CR from kills while you simply have the standard CR of only one unit! (I've screwed up and allowed this once or twice and haven't done it since!)
I can also make anadditional article on using multipel units to fight multiple enemies in a larger article covering the Reman Legion's army tactics rather than individual unit tactics like this article covered. But seriously, the Remans are nothing more than several smaller units working in union to make a solid, invincible wall. Each parent & detachment combo can easily defeat any enemy unit out there and when all work together thay defeat entire armies!
