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.
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.
