Ghost Recon

On any level in the game that involves a tank in it,(including enemy tanks if you can get close to them) You can crawl under the tank by getting in front of it,and laying on the ground and crawling backwards.Once you`re under it,stand up and walk with it.This will give you protection.

When you meet up with the allied tank go forward. The first building on the left will have several soldiers in it. One man has an anti-tank rocket. Eliminate him as soon has possible to stop him from destroying the allied tank.
