You can counter an incoming grab by blocking. This is only effective if you have enough health and against grabs from the front.

After knocking the "radio transmitter", you have to kill all marines in the area then go through a gate. After this, your objective is to enter a building with an unarmed civilian inside. To do this, you have to find a vent between two buildings. Start at the main gate where the electrical fence is broke. There are two buildings on the right. The vent is between the two little buildings that create an alley. The vent is at the start of that alley. Note: If you go to the end of that alley, you can turn left at which point a turret will shoot you, or turn right to find a wall that leads to the main gate and the generator. Once inside the vent, follow it to an very small vent with smoke coming out of it. Use it to enter the building.
