on some of the chapters during the game, you cannot proceed or enter a building or
transport until all your men are with you. call them to you with the x button, you might
have to press it more than once. press your right joystick in to bring up the radar and
you will see them come to you, then you will be able to proceed.

im having the same problem... kill all the men or whatever, but the barricade is still
there, and theres no rocket launcher on the right hand side of the building, just wall.
even when i call the men we just end up standing in front o a closed barricade. did it
work for u in the end?

sometimes the guy doesnt bring the tank.... u have to restart the level again
