WWII USMC Officers 6th Division Uniform WIA Okinawa

[Chrisusa1]

Hi all,  

 

I've had this uniform for many years, and only recently began to do some research on the original owner.  Uniform came into my possession with all the insignia and ribbons as shown, I believe they are all original to the uniform, ribbons are the waxy type with pin back attachment.  Per his casualty card he was wounded by shrapnel on May 16, 1945 I think likely while attacking Sugarloaf Hill, and was evacuated to a US Navy hospital in Guam.   Per his casualty card he was attached to the Recon. Co Hq Bn. anyone know if this is a specialized unit and a predecessor of modern USMC recon. units?
