Well you all seem a shy lot
so I will start the ball rolling: I call this the first wave impact
Take one army preferably either Empire, Bretonian or High Elves (Works very well with High Elves). Base points 1500pts. Take three characters, two must be mages one can be acharacter or a Army Standard, have one small core unit and one rare choice, the rest points out on cavalry. Have the mages on foot, the third character on horse.
The objective of this is to get as much heavy cavalry you can for the most poinst cost effectiveness....
So taht on initial set up you make a long line of cavalry from one edge to the other. Obviously you may not get from board to board edge...but you certainly can get a decent line.
High Elves are much better at this from experience as they have the most versatile use of magic in spells and banners.
So you have you nice long line - let say High Elf Silver helms. Banner (25pts max), Champion and Muscian mixed in - One Commander to Army Standard....so how to get across the board with out being massacred...
Options rely on magic here - Shadows and Life. If you want to be really nasty take three mages ( but this is getting expensive and looses some fire power out of the rank). Shadows gives unseen lurker....so taking shadows twice (Yep Seer gift on each mage).....
Then add the Ellyrion Banner in (gets rid of uneven ground)
If you ahve the army standard then add either Battle Banner or Banner of Balance (this kills those frenzied units)
So you now have a potential charge from 14" to a massive 30",
Combat is worked on the percent. The enemy already out numbers you, has three ranks, banner etc base in their favour 5 (6 with war banner).
Now the charge is aimed at one unit but becuase of the long line it will hit several regardless. Always aim for shooting units first - these are the weak link in any army. When you hit one of these you are bound to hit several ground units. The advantage here is taht you will cause massive casualties Average chanes to hit is 3-4 D6 so a sizable cavalry charge will have out of 20 figures will hit on average 9-10 (not inc Horses here). So this will normall happen on the shooty unit - no reprisals from them an more likely the unit will almost be wiped out. Horse may add another two casualties - end result is that you may take one or two but the combat swings in your favour and has a high probablity of breaking a large part of the enemy force with in one turn.
The firepower is provied by 10 archers and 2 repeater bolt throwers, these can rake any serious threats to the cavalry charge and enemy war machines
It is putting all the eggs in one basket, and can end distasterously if it fails. But it is spectacular either way 'Into the Valley of Death.....' Love it
Of course this doesn't take in consideration the oddities out there, but I have used this method on numerous occasions against undead Tomb Kings and Vampire Counts, Empire, Chaos, Dark Elves, Lizardmen and Bretonians - I have varied successes - but the only real army I fail against was the Bretonians.
Yet to try against skaven -
So come on what is your favourite tactic.....
