How do you get into chautue on 1st mission. None of my men will go into either entrance

When you enter a building or confined space sometimes the GI Soldiers in your squad won't follow because they get caught up in a corner, wall, ect. It's a computer design flaw. Just go back to them and hit "F" key to follow (they should follow). Another way to help is hit key "E", the squad will follow in "Ranger" formation (in a straight line behind the "point man" or lead man). This will also help them follow a bit better without getting caught up easy. Keep looking back and making sure they are following, because their added firepower helps keep your squad alive. One more tip; if you hit the "control" key your squad will "squat" and keep their heads down. Being in a "squat" position will make your squad a smaller target (however they'll travel slower). One last tip; save alot too!
