Based on your decription, I would say either the Monastery or the Backroom, depending on the content. Humor about military history is still commentary about military history and thus I would say it belongs in the Monastery. However, if some of your jokes are excessively controversial, the proper place for them would be in the Backroom. I would post first in the Monastery, with subscript to Kraxis and CBR to move them to a different forum if they think they do not properly fit that forum.
