Low visibility and lack of targets limited the fires to a few rounds the first night. Next day the artillery landing was completed when 4/11 went ashore on RED Beach, followed on D-plus 2 by the 96th Field Artillery Battalion, USA. Plans for the drive inland called for 1/11 and 2/11 to fire in direct support of RCT-5 and RCT-1 respectively. Support was to be provided by 4/11 for RCT-5 and by the Army battalion for RCT-1.[180] [180] 1st MarDiv _SAR_, Annex Sugar Sugar. The problems of tank support for the Inchon operation had given the planners many a headache. BLUE Beach was dismissed from consideration because of the mud flats, and the possibilities at RED Beach were not encouraging. GREEN Beach offered the best prospects for landing tanks, though it was recognized that they would be stranded if the enemy destroyed the causeway connecting Wolmi-do with the mainland. The consequences of the hasty embarkation from Camp Pendleton had borne down heavily upon the 1st Tank Battalion, commanded by Lieutenant Colonel Harry T. Milne. Crews trained with the M-4A3 (Sherman) and 105mm howitzer were suddenly equipped with the M-26 (Pershing) and its 90mm gun. With the exception of Company A, which saw action with the Brigade, few of the men had had any experience either at driving or firing the new tanks. The flame tank platoon of Headquarters Company had received some training at Barstow, but most of the personnel of Baker, Charlie, and Dog Companies were limited to shipboard instruction. The men of the Company A platoon which landed on GREEN Beach in support of 3/5 were veterans of several fights with NKPA tanks and infantry in the Pusan Perimeter. In the evening of D-day they supported the landing on RED Beach and moved across the causeway to the mainland at dusk. There they joined the other two platoons of Able Company and the flame tank platoon, which landed with the LSTs in support of the 5th Marines. At 1700 on D-day a reconnaissance team went ashore on Wolmi-do to prepare for the landing of B Company, which took place late the following afternoon. YELLOW Beach, in the inner harbor, was operative for the landing of Company C on 18 September, and Company D was to arrive later with the 7th Marines.[181] [181] 1st MarDiv _SAR_, Annex Oboe Oboe. _The Attack on D-plus 1_
