Regards the 'walk through the battlefield' level - are you aware by holding down the LMB you recharge your health? You have to take it slow and if you lose health, recharge to the full. But also avoid getting run down by one of the tanks. There's a trench in the level on the way to the exit you should follow - if you try to go up and over you'll attract extra fire.
As for the training level - it plays the same as the demo. In terms of tactics, keep moving and zigzagging - you may need to hang back if there's 2 or more enemy tanks and remember to hold down the LMB when you can to charge up your shots. But you'll have to use judgement when to release a charged up shot as any damage and you'll lose the charge.
Finally, if all else fails, hit the tilde key and type 'god' to go to godmode.
