Ah, I didn't realise you could open that gate - will give it a try - thank you

Yes, that's exactly what I did, and I have taken all of them out except for this last one which is near the CC, on a cliff and behind a gate, and I can't seem to find a location that will allow me to get a shot at it - very frustrating to say the least. I am sure I am missing something simple

There is an AA nest near the command centre which seems to me to be impossible to get a shot at with a walrus, and mantas can't be used until the AA nests are destroyed. Can someone point me in the right direction please?
