Newbie: Which PzC game to begin?

[Drakken]

I fiddlled around with the Operation no.3 scenario (the getting started one) to get started. Used my troops very stupidly, took em whole turns to understand how to use my Engineers to build a bridge, but in the end finally got around to take at least one objective despite heavy losses. Oddly, when the scenario was over and the FOW was lifted a whole Division (34th IIRC) was sitting on the road North of Orsha in neat position, doing absolutely nothing. Did the AI fall asleep, or is it the way the scenario was written to give a starting player a fighting chance?

then I started Operation no.1 (the one to practice fording over a River going through the whole map). Finally got to understand how to use my troops (and my artillery) efficiently, the principle of disruption, planning movements, using Soft vs Hard attack, Assaults, etc. By the end of Turn 10 (on 16) my whole troops had passed over the River, I already had the 3 objectives, isolate a whole stack of Rifle Divisions, and annihilated them with far fewer casualties. I'm proud of my learning progression, but it's against the AI so I mustn't pat myself too hard on my shoulder.

Bigger maps, though, seem more daunting.

I got a question, though. Glacing at the supply rules and the map of bigger scenarios, is it possible to use tanks to create big pockets on bigger maps, or even have a bonus for attacking from the rear? From me reading It seems impossible, troops become isolated if and only if all its surrounding hexes are within enemy ZOC within close range. It seems odd JT had no provision in its rules for encirclements, as it was a pivotal aim of combining arms in blitzkrieg.
