Coup d'État: A Practical Handbook, Revised Edition (2016) by Edward N. Luttwak. Pages 60-62

The first edition (1968) is timeless, but the revised edition (2016) is amazingly on-point and is updated to reflect the structural changes which have occurred in the half century since it's first printing. It's only 300-odd pages, highly recommended.

No. Erdogan called for people to take to the streets, and within an hour, the airport and bridge were filled with thousands of people waving flags. (From pictures, all male.) That's popular support. The military is not attacking the crowds. The military presence was apparently not that big, concentrating on a few key spots.

A coup has to succeed within the first few hours. Control must be established before opposition mobilizes. If the coup drags on, it fails. Failure is either a loss or a civil war.
