How to destroyed all tanks in igi 7 level and tell me how to win 8 level?

Re-supply can be won by destroying all the alarms.after you get out of the truck you will see the
Green crates .jump on them and get out of the infantry base before the tank coming.in border crossing first
Kill the soldier with knife and get to the slam in front right and crouch with ctrl .then hit the soldiers with dragonav.get unlimited ammo by creating a shortcut of igi in desktop and right clicking on them and going in properties and you will see target there you give a space and write unlimitedammo. Then go in the peak of a mountain before the truck,kill the man with uzi>the tiger tank will come out get past it on the mountain kill every person with draganov get the weapons and you will see a tank past the barrack just get the law80 in the barrack and shoot the tank get in the tower and kill the people and destroy the alarms with sniper then open the border with the keys and quickly get into the truck. There is a cheat of getting invisible and the soldiers can't see you but tanks,sentryguns and helicopters can see you .just go to igi in stalled folder an go to pc make a backup of ai file in common file and get in ai file delete all files except settings and observer .makee 10 copies of observer and name them as files you have deleted.good luck
