[RANT INITIATED]
I've noticed playing online that many users will have at least six mortar units in their armies. They practice 24/7 on a mountainous map, always use landscape obstacles and height advantages.

I don't know all the maps that well, and when the enemy knows all of it, your already at disadvantage.

I'm the more traditional kind of commander relying more on cavalry and infantry. I usually just have 2 mortar teams in my armies. When I have to face this every time, it can be quite difficult to win, and I still get pretty darn close winning some times.

Even more seemingly old fashioned, I almost kinda feel it dishonorable. I mean 6 mortars raining down on your infantry, and by the the time you get in range half of your troop gets decimated. If half of your army is already killed, then it almost feels like your men don't have a chance. Staring at mortars with wooden stakes in front, light infantry shooting down your men as they walk up hill while still out of range... and there's still that elite guard up there... It can be a VERY demoralizing sight indeed.

Why make a big fuss? Why not just play a quick land battle?
Well most land battles are played with the smallest unit sizes, and it's a turn off for me.

Any tips?
Here's what I already do when I join a game. I just pray the enemy doesn't have a huge mortar battery waiting for me at the top of a hill...

1 General,3-4 Heavy/Lancer Cavalry (Sometimes some light cavalry elements), 2 mortars, 6-8 of the most elite infantry.

Now, I'm starting to incorporate light infantry to my late army because of their range, but for now I'm still developing tactics on how to use 'em.

If I AM against someone with a huge arty squad:
1.March as QUICKLY as possible without tiring the troops
2.Arty targets right flank of the enemy
3.Once I get in range, I use my usual gameplan:
4. Infantry engages
5. My column of cavalry all on right flank, gets in position to flank and target either:
1. Other Cavalry 2. Light Infantry 3. Regular Line Infantry 4. Arty
6. My first line is about 5-6 infantry and a second line as reserve with remaining infantry. (usually elite) Reserve either fends off flanking cavalry on the left flank, or help with main engagement
7. If flanks are clear charge the enemy, and general joins in to help out any struggling regiment
8. If the cavalry removes all threats on the flanks then, they help mop up the main engagement

The strategy is to overwhelm the right flank whilst holding the left from any flanking maneuvers. The right flank folds, and each unit on the right rout one by one or altogether eventually leading up to the left flank. If the cavalry is not successful enough, then the chance of defeat increases, depending on the situation.

Of course if one step is already competed and/or not necessary, then I skip steps.

So again any tips, thanks in advance.
