We learned a lot about F&I war up here because it largely started and took place here... We had an odd focus on that when I was young. The Revolution, really practically skipped all combat and just focused on the documents, founding fathers, etc.
I never had a class on WWI, WWII, etc. Seriously. We got to the Civil War and that was usually where it ended. Lot of focus on the Civil War though, not just the politics but combat, daily life, etc. Both history teachers in my school were big into that and since I re-enacted at the time (signal flag kid) they used me heavily to bring crap in and talk about it. I didn't even have to take the final.
My gf's boys seemed to cover everything... I helped both with WWI Trench dioramas which were their project for that era. I should post the little dioramas we made in a weekend. I guess that should be "we" made.
The boys picked it knowing I'd go giddy making crap for them.
