Wow will give it one last go & cover a few points.
PBEM I nearly always use XXX rating, adjust it only if decide one player needs an advantage.

This game is about battles & war is NEVER balanced it cant be because there are so many factors involved even if you did say Germany vs Germany with identical forces it would not be equal.
You have taken troop quality & equipment (technology) out of the equation but there is still terrain, tactics & plain old luck.

As its about battles & its generally accepted you need a 3:1 ratio when attacking prepared units that's what the game uses.
Why because its the norm.
If you want to use a different ratio from 1:1 to 10:1 that's fine they have happened.

As an example as you like Squad heavy sides Korean War so 1950s, sorry cant remember name of the battle or a WWII with high odds.
China attacks British in a river crossing with odds of around 10:1.
They won but at horrendous cost, the British withdrew leaving a company & their artillery to cover the withdrawal.
The artillery was no use to them as most were malfunctioning due to the severe use, they used virtually their entire stock of ammo in the battle (cant remember was supposed to last 4-6weeks)

The Chinese commander said he had won the battle but lost the war because the Chinese losses were so huge.

The reason I mention this is the game would list this as a draw or victory if you can replicate it, I have tried & I can never do as well as they did.

My point play what you want 3:1 is just the norm & with a bit of experience you will win most of the time. Many people will play with worse odds because it makes it more challenging.

Its all about developing or using RL tactics & rising to the challenge.
You can adjust the challenge as you so fit either with points balance, beneficial terrain, vision settings, playing the underdogs or superior side.
It will never be balanced though because this is war & you can out think the AI.

Said my piece keep playing & you will find you start winning this type of battle & perhaps even making it harder further down the road.

As a side note if you want unbalanced try using MBT so modern battles a major power vs a 3rd world one. I don't do it to often because it fries your brain but its amazing what you can pull of sometimes.
