Can someone help explain the difference in Tiller games?

[Richie61]

What are the differences between the Squad Battle series over John Tiller's Campaign Series?

I read that not all of the Sqaud Battle games have the 3D view?

I like that the Campaign series has all the nations OOB's in one game.

If someone could help educate this noob on the differences in the games I'd appreciate it.

Thanks!

I am guessing this is Bruce? 

I am not a Campaign player. I have it and it does nothing for me, but lots of people love it.
Platoon-scale tactical game.
hexes are 250 meters

Squad Battles (my thing)   Basically a Squad Leader type game. Leaders, squads and single weapons like guns, tanks, half tracks.

The game scale is 40 meter hexes and 5 minute turns.
Units are normally at the squad and single vehicle level.

Start with Red Victory
