About five-thousand Marines will be arriving in Kuwait this month for duty in Iraq in July.
The rapid-fire deployment comes during intense summer heat and tight scheduling. Troops will be expected to land for war duty a few weeks after getting the order.
The Marines will be among the units heading to Iraq to relieve about 15-thousand war-weary soldiers from the Army's First Armored Division and Second Armored Cavalry Regiment.
The incoming Marines will be sent from Camp Pendleton in California and Camp Lejeune in North Carolina. They'll spend about 20 days in Kuwait, unloading their gear, practice-firing their weapons and getting used to heat that is already above 110 degrees.
They will be followed by 36-hundred Army infantry division soldiers based in South Korea.
