turn around a bit
usualy they come form 2 sides.
i think thats the bit were the jeep has to go ofroad cause a german truck is on the street (after you pass a convoy)
whne you r driving towards this smal roadbock.
shoot at the truck standing there it wil explode and kill the 4 germans behind it.
now do a 180 turn cause at the other side there r 2 buildings with a shitload of germans coming from them.
