... small wars, of course! My own list is below, but what are yours? What insights and knowledge can we gain from the experiences of insurgents and counterinsurgents in these unjustifiably overlooked wars?

The Rif War (1911-1927)

Egypt in Yemen (1962-1967)
Syria in Lebanon (1976-1990)
Sri Lankan civil war (1983-present)
Haitian Revolution (1791-1804)
