I am stuck at the mission, 2 I think it is, where you gotta put on a German uniform and destroy that radar thing and then blow the sub. Major Grillo gets killed when he opens the gate and tells you to go without him. I am at the part where you gotta put on the German uniform and blow the sub and destroy that radar thing.

I show the guard at the bottom of the stairs my papers and he lets me in. I go in the room with the scientists and the radar thing and the don't bother me. There is no where else to go 'cause all the other doors are locked. So I destroy the radar thing and all the scientists freak out and start shooting so I wax 'em. This puts the whole base on alert and all the soldiers come shooting at me. I killed them all and tried to get to the sub but there are so many guards that just keep comming out of this door on the right down by the sub. Do I just gotta keep shooting them and then they will stop or did I do something wrong here?

How can I sneak when destroying the radar thing instantly raises all the alarms? Help, stuck here pretty bad!

Umm.....
Go away....
No one has it yet....
Exception of warez and lucky people....

After you blow the radar and come out of the sub, the door to your left should open after killing some guys, and you need to go out there.
