I ask not about lawyers who serve as military lawyers.
in the former, Colonel Dax, a criminal lawyer, portrayed by Colonel Dax, who blows the whistle before going over the top to lead an infantry assault against the Germans.
in the latter, USMC CPT James Staros (portrayed by Elias Koteas).
Would these lawyers have already been trained or served maybe in the Reserves, before the war and before they were called for duty?
Or could a lay lawyer, entirely ignorant of the military, be trained and prepared only in the short time after a declaration of war?
