I have trained myself in poles, pole-arms, pole-axes, hand thrown blades and poles, hand blades and daggers, short sword, full swords, katana, open hand, Hokkaido and Iaijutsu.
I have been trained in firearms (general), semi-auto break and magazine loading pistols, semi-auto breach, loaded and magazine loading rifles, automatic magazine loading rifles (Military Qualification), Belt-fed rifles (Military Qualification), M2 (Military Qualification), M203 (unqualified), AT4 (unqualified)
I and also load, calibrate, aim and fire the M230 as well as fly the AH64D but I don't know how you quantify that in this scenario because I was only trained load and calibrate the gun.
