Everything I’ve seen states no wood so here goes;

Looks like wood siding, sand or concrete filled, M4A2 from 1st TB, and for a little more positive ID, it sure looks like T-6 Flotation attachments, only placed used is Okinawa.
For a little more background this came from a USMC documentary. I know you can’t believe everything but here I am at a loss.
Any ideas or info would be great,
Bob
