When starting the campaign (so first movements, no battles, no other units moved in the path) the furthest I can get with armoured elements is 85 km (recon on a highway) when at the same time the infantry regiment can cover 50 km. Am I doing something wrong here? I mean for 3.5 day turn this a pathetic distance for a recon unit (tanks can only cover same distance as infantry).
Historically on June 27, 2nd and 3rd Panzer Groups met up at Minsk advancing 300 km into Soviet territory . Seems like I'm doing something terribly stupid or something is set up wrong as I cannot get more than 200 km in 2 turn and only with recon elements

Another two things of more general nature.
Why it is not allowed to transport unitsby rail in one go? I mean 200 km by train was in-and-out operation for a day. And within 3 days that should still allow for some fighting.
No chance of getting the semi-automatic digging in? There is no added value (just wast of time) to having to dig 'em all manually. One I order them to dig in they should be digging in until order otherwise.
