My personal "Basic Integrated Curriculum" is

Wrestling:
Sprawl
Clinch
Bodylock takedown

Striking:
Jab
Cross
Hook
Crazy Monkey guard
Low Thai kick

Grappling:
Basic Positions
Mount Escapes
Side Control Escapes
Scissor Sweep
Situp Sweep
Back Control
RNC
Arm Triangle

That's for "Self Defense". If some regular dude studies that list for a year they will be well equipped to handle 99.99999% of all unarmed encounters they will ever have. They don't have to make any decisions about breaking peoples arms. They know how to escape from bad positions and they know how to subdue someone on the ground.
