Have you received training as an enlisted person? Because PPTs are but one - of numerous - ways, to include drills, exercises, and other physical doing.
Yes, 12.5 years enlisted. I've sat through more dumb PPT's that are a reaction to an incident than I care to remember. With Covid, the model seems to have moved to doing an online course which is a bunch of slides and some multiple choice questions.
Experience varies. I've enjoyed all my postings, some more than others and I don't regret enlisting for a second. But I've certainly seen a lot of reactions to make incidents in the form of watch a video or a PowerPoint presentation. Not so much for proper training.
The cutting edge in mediocre corporate training at the moment is drawing pictures about experiences based on open ended questions to which no one dares say an answer is wrong but instead passively aggressively use voting via small tags of coloured paper and resulting in nothing aside from a few quotes from self improvement books, and a cake and photo at the end of the day to *celebrate the journey", and that shading stick figure figurines with grey makes them look better.
