In case anyone is curious, Yang has a pair of what are essentially M1917 Smith and Wessons, and a Fusil Automatique Modele 1918.

EDIT: I worry that Yang's lessons are going to be clouded by my research: I'm spending hours every day reading field manuals and books about counterinsurgency. It'll be nice to have an excuse to read other things, I suppose: COIN is bullshit.
