“Defensive Tactics With Flashlights” by John Peters (1982) pp. 156-158.
The chart is from Juste David Myers – the work cited was an unpublished manuscript (“Close Quarter Combat” 1982), which doesn’t appear to have ever gone to print. Nevertheless, the matrix shows a presumptive survival ratio based on physical size.
Peter’s book primarily is an instructional manual on the tactical use of a large Maglite style flashlight. However, in his MAG 20 class, Massad Ayoob referenced this book for the Size=Disparity of Force matrix, which is linked above for your reference and self-defense library to augment your understanding of the use of force – AOJ.
There is no substitute for expert instruction – seek it out.
David and Goliath: The classic size – disparity of force confrontation. Goliath clearly demonstrated ample ability, opportunity and threatened jeopardy. David armed himself with an effective range weapon and stopped the threat. >more<
