There was, at the time, not a significant population at the post and it was not heavily patrolled. However, the high-security areas were a wholly different matter and there was a significant security presence in those areas.
To be fair, I have not been there since early (January/February) 1997. Things have undoubtedly changed in terms of operations. I still have civilian friends up there and know a few people stationed there, as well. I think we’re in pretty good hands.
Ft Greeley enjoys the same protection as our ICBM fields.
