Wolf, again, I don't disagree with you.
But we cannot simply divide 600 km by 2 X 10hr/day to get the speed the tanks were travelling at.
an armored division would have ~300 tanks? maintenance platoon of 600+ men + engineering vehicles, +8000 men in 200 APC/IFV and ~1000 trucks, organic artillery.
Thats a column length of 30 km just counting the vehicles at 20 m spacing,
Now, each one runs out of fuel in around 4-6 hours, Refueling process will take, 4-6 hours just to refuel the column and several hours for the trucks to actually get there driving up and down the column to reach each vehicle. +rest stop, +meal break, +terrain choke points,
The armoured column may only really be moving on the road 5-6 hours a day; probably a sustained road speed of 45-60 km/hr
The gulf war had shown that some Abrams that were advancing 100s of km a day in Iraq simply sat there for days waiting for fuel to catch up.
Come on, that smacks of manipulating the figures to suit your needs.
I was already being extremely generous knocking travel time to 10h a day. That subtracted 14h per day is for rest breaks, refueling, sleep and all the rest, and is beyond reasonable.
To only spend 5-6 hours per day traveling, during a maneuvering exercise, would be scandalously incompetent. That would be pretty poor even for your average family holiday road trip, and those are supposed to be soldiers on a mission, not civilians out for a leisurely drive.
Again, your Iraqi example doesn't prove much. Going at 30kh/m nets you 300km per day if you are driving 10hs. Hardly unreasonable figures, especially for the ideal tank terrain they were operating in.
You are not going to find any examples of tanks travelling hundreds of KMs at top speed because that just isn't done. The tank engines are not designed to be pushed that hard for that long, and if you tried it, things will break.
Hell, those top speeds are usually not even attainable unless under ideal conditions. Things like your tank with minimal load bombing down a very straight stretch of highway or perfect plains/desert conditions. Even then its not really advisable outside of a test facility as everyday things like large pot holes or large buried rocks could potentially throw a track if your tank is moving that fast when it hits it.
