I asked the U.S.Army historical LLibrary and recieved this response:
Sir,
I've found very little information on the Army Defense Battalions. I know the
3rd and 4th Army Defense Battalions saw action in 1944 in the Middle Pacific. We
have some TO&E's, particularly for 1942. I searched through the 1942 TO&E's and
did not find one for the Defense Battalion. I do not know if they had a specific
organization and associated TO&E but I suspect they did because the Marine
Defense Battalions had TO&E's. My guess is that the Army created TO&E's for them
after 1942. We don't have TO&E's in our collections here for 1943-1945.
Here's some info on the Marine Defense Battalions: <

I'd suggest you contact NARA, they should have TO&E's for all army units of
World War II at their College Park location. MHI probably has them as well, but
asking NARA for them would be a lot faster. MHI tends to take about 6 months to
answer a question, and has patrons go to them to use their materials.
Here is the online question form for NARA: <

you'll want to fill out the "I have a question about research and records at
NARA".

I hope this information is helpful to you.
