I want to know the answer to the following question:
What Corps included 40,000 men from the 1st Marine Division?
All the background I'm provided with is that "The X Corps, led by General Edward Almond, Commander, consisted of 40,000 men of the 1st Marine Division, the 7th Infantry Division and around 8,600 ROK Army soldiers.". Is that enough to answer the question?
Answer: yes
