This is true. And I don’t think Hartmann ever modified his, “See-Decide-Attack-Break” strategy for anything except for aerial combat while Boyd seemed to spread his out to encompass war strategy, business, leadership etc.. From what I read of Hartmann, he always broke & started back over when safely out of the battle zone so that was kind of a loop? He always went after the low fruit the same as the lion goes after the slowest gazelle then run away. He said he never engaged unless he was near certain he could get a victory. He wasn’t known for dogfighting, more for shooting bad or unfortunate Allied pilots out of the air.
An odd thing about Hartmann & his strategy. I don’t remember the first time I read about him but the last time was overhearing about him on a random YouTube/Podcast my kid was listening to about video gaming? Those video gamming nerds are using WW2 strategies to rack up points & stay a live in video games?
