Stop in for a cup of coffee

OK don't tell us what the course is....
Math and trig never heard of trig in anything Army or anything I ever did??
Math work could be a lot of things.
No Power Point the Army lives by PP or maybe it's just feed to your iPad??
Things have changed since I retired 13 years ago.
It’s Range Development and Safety Advanced course. I mentioned it earlier this week. Basically learning how to build ranges and impact areas

Nope, there is zero technology allowed. The instructors are even not allowing calculator use. It’s like I’m back in school way back when lol.
