Oh I was assuming you'd doing diaphragmatic breathing when you used you're diaphragm to yell. Which I think would would be no? And then what I was really asking wouldn't you be able to take the breathing technique you used in the training and apply to normal conversions albeit with less volume. And you seem to have answered my question so thank you for that! And thank you also for explain the circumstances regarding your admission into the Space Force. So you didn't have to take the test that everyone else does? How did they evaluate your cognitive and technical ability if they didn't test you?
