Bogging down, and immobilization

[Der Kuenstler]

Yes - the best thing to do when a vehicle is bogged is cancel all orders and put it in reverse a short distance. Much of the time it will unbog after a minute or so.

AFVs will bog the least on roads, and more in trees, rocky, brush, etc. I have also noticed they will bog more in LOW GROUND. I was playing a recent ME on wet ground. I lined up three stugs on the start line in low grassy ground to assure that they would not be seen by the enemy - but 2 out of three bogged and became immobilized before they even went 10 meters.

Yes - they do bog easier when moving fast. Less experienced crews also bog easier. The safest thing to do is buy vet crews and stay on higher grassy areas and roads when going fast, and in other areas using "hunt."
Sometimes they bog anyway though - just a random factor.

Smaller shells often don't knock a tank out when they penetrate. The best thing to do is watch the tank after it gets hit. If it stops moving suddenly and stays perfectly still or stops returning fire, you've probably knocked it out.

Someone else will have to address the pushing of bogged vehicles and exploding shells - not sure on those.
