What was not a military strategy employed by the american expeditionary force in 1917?

a. complete reorganization and modernization of the army
b. increased use of tanks and artillery
c. u. s. army troops fighting under foreign command in europe
d. limited use of trench warfare

The use of a limited trench of warfare was not a strategy taken into account. The American Expeditionary force was reorganized right before the troops were sent to the batlefield. Actualy the General in chief suggested a military training for the force. Even though the general in chief did not want them to be commanded by a foreing force, they had to be commanded by french division armies in different ocassions. Many of the tanks and artillery were supplied by the allied forces so that us troops may also use tanks and artillery. A trench warfare strategy was not considered
