RTC Building Identification Help Needed

I was looking over a map of RTC and am having trouble identifying a few buildings.

1) Two buildings very close to one another, one square, one rectangle, immediately south of the Photo Lab and NEX.

2) The long rectangular building running north/south that is immediately north of the SAM-T building. I imagine this could be an addition to the SAM/T facility.

3)The building to the south east of the USS Marlinspike.

Here is a quick link to the Google map of RTC if anyone needs it: http://g.co/maps/u95qr

Thanks,
