Lt. Banks wears the Air Force's Outstanding Unit Award. Even if he had been in the Air Force previously, on an Army uniform this award would have been worn over the right pocket above the name tag.
Col. Drake does not wear his awards in the proper order. He wears the Army Commendation Medal as a higher award than the Purple Heart. Also, he wears an Air Force and Navy unit citations with his ribbons. Assuming he had been in the 2 other branches of the military, these unit awards would be worn over the right pocket above the name tag.
Shoes are visible on the Hulk's feet when he pushes the tank.
When the yellow canister is first thrown and rolls down the hill the valve is missing. When David later retrieves the canister the valve is back on.
The Doctors Lounge sign should read Doctors' Lounge.
When Banner is being examined, his face comes slightly into frame on the left, and his mouth is moving but his voice is not heard.
The family's name is Banks, yet the mailbox outside their house - visible when Jerry Banks is first shown coming home - is marked "The Banks", as if their surname was "Bank". The mailbox should instead read "The Bankses".
