Marine Corps tactics called for bypassing single snipers or machine guns in order to keep forward momentum. Bypassed Japanese we knocked out by a platoon or company of infantry in reserve. Thus mortars fired furiously on the enemy front while a small battle raged behind between bypassed, entrenched Japanese and Marines in reserve. These Japanese frequently fired from the rear, pinning down the advance and causing casualties. Troops had to be well disciplined to function this way, and leadership had to be the best to coordinate things under such chaotic conditions. Marine tactics resembled those developed by the Germans under Gen. Erich Ludendorff which proved so successful against the Allies in the spring of 1918.
