"Seizure of the Marianas turned the Pacific war. Their loss cut the Japanese defense and placed Japan within bomber range. Operation Forager saw CBs make significant contributions at the Kwajalein, Saipan, Guam, and Tinian. On Siapan and Tinian top secret Seabee handiwork was fielded by the 2nd and 4th Tank Battalions, flamethrowing tanks. Within four days of capture, Seabees had Aslito on Saipan operational. During the battle for Guam, CB Specials did stevedoring while others were Marine combat engineers. When they were done CBs turned Guam into a Lion for the fleet and an Oak for the air corps. The invasion of Tinian was a showcase of Seabee ingenuity and engineering. The CEC engineered detachable ramps mounted on LVT-2s making landings possible where the Japanese thought it was impossible. Before the island was even secure, Seabees were completing an unfinished Japanese airfield."
