I can only refer to my field battles strategy which usually remains same in every battle...either assault or defence :
Well....In a normal campaign scenario...were due to lack of infinate money i cannot field always an army full of elite units i use a concept which was used by ancient Greek Phalanx armies of Athens in order to crush enemies even against great odds asf (well with a few changes as at The Battle of Marathon the Athenians did not field any Heavy cavalry or cavalry at all hehe

:
------ PLS CLICK ON THE THUMBNAILS FOR A SCEMATIC APPEARENCE OF EACH PHASE ---
PHASE 1:
M: missile Units
I: Infantry (Either Heavy or Normal or Light)
S: Spears
C: Heavy Cavalry (Kataphracts since i play the Byzantine Empire)
L: Light Cavalry (Stratiote or any kind of Light Lancer BUT NOT mounted archers)
I split the army in the following groups as swon in the drawing.
PHASE 2:
Now on the next phase of the battle i forward the whole army towards the enemy at shooting distance in order fr my missiles to start shooting but must take care not to change the distances between the groups. Now the important thing is that the AI while on frontal attacks tends to attack your "weakest units" first... 9/10 times. That is very critical fr the abv strategy to work...So if everything goes fine and the enemy is lured in the center...(you got to help this happening by projecting a big frontal area with your missiles and harrassing the enemy's centre by skirmishing..running back and forth faking a melee attack with secondary wepons etc..) the battlefield should look like this:
PHASE 3:
Now in the 2nd phase of the above startegy as you can obviously see this gets you into a position to DOUBLE ENVELOPE the enemy's centre by a crushing double flank attack from your wings while he is trying to kill your missiles troops (Important.: i have noticed that you need quite a few missile troops to be able to lure the enemy effectively).. Please note that you do not attack with every unit in you flank...as you noticed the rear ranks of my flanks are spearmen..(or pike if you want) the reason is that after you envelope the center..the AI usually charges its Cavalry at your back to brake the encirclement...so the tactic is shown as following(in the meantime my Cavalry has taken its time to go a long round trip behind enemy lines):
At this phase there are 3 possible outcomes:
1)
After a while the central enemy units route..if not totally anihilated at spot. If the enemy cavalry charges at your flanking units you have the spears readied for them... You cavalry comes from behind and finishes of the enemy cavalry which is entangled in your spears...You know the rest....chain routing...Victory within a few seconds...
2)
If Enemy's infantry units are top quality/elite (usually my case especially during late era

) so they dont get damaged enough even with the double/triple flanking (with the counter attack) tactic shown above. When this happens they do not route and AI reasonably sends the rest of melee or even cavalry troops to create a big messy "sandwich" at the centre looking something like that:
As you can imagine you begin consecutive cavalry charges in the enemys rear hoping to break them and start routing...you can use light cavalry then for capturing routers.
Final Phase:
There are a few advantages and 2 BIG disadvatages in this tactic which are asf:
1) It Can give you victory even against great Odds. With WAYYY to many enemy casualties..enemy does not just flee...they get Anihilated

.
2) Very Fast... Most of the times the crushing attack at the centre terrifies the AI armies and they Flee battle within a few seconds (Yes i know about the full cavalry army and the frontal charge...but its not realistic...im talking about balanced realistic synthesis of an army with all basic kinds of units)
3) Gives you control of the battle to a certain extent. You get to control the engagement. Does not necessarily need all kind of elite troops..but good versions of the basic 3...Infantry (mixed with Spears) , quite a few Missiles just for luring the enemy in center and thus becoming the "bait" for the entrapment (achers with sec. Sword?) and a good load of hevy cavalry including your general's bodygrds).
Disadvantages:
1)If the enemys majority of melee troops have better stats than any of your infantry then the whole tactic goes to waste because the centre does not break even when encircled they do not break but instead they kill all of your flanking troops...in this case only way to anticipate is to flank them only with one wing and leave the other flank of their central attacking units open for charge by your cavalry. At this point your wing which skips the flanking attack should march even further to intercept any attack to your charging cavalry as shown:
2) The second and biggest problem of this tactic is that it is VERY VEEEERY deifficult to perform.... Needs perfect timing....and needs to move all different wings at the SAME TIME and accurately...Believe me..in same battles with same General's stats, same enemy units, same all things, i have had different outcomes due to a slight inaccuracy of handling the units (one wing marching just a bit further than the other...cavalry not lined up fr charge on time or not chargin to good due to terrain abnormalities...spears not placed too tight in the flanks pointing outward...) Needs a lot of practice to master...but if you perform it correctly and Accurately you can achieve heroic victories.
That was my humble battle tactic.. Well its not just that cause it has many more Micromanagement in it but it will take too long. Pls feel free to ask me fr any clarifications that you may need.
Pls kindly let me know of your opinions/ suggestions.
P/S: pls forginve my English...as for the Drawings i know they look messy but i had to do them in simple MSpaint...i hope that you get my point though!
