I just found this images of a stell shipping container for Javelin missiles. It´s a long shot, but can anyone identify it?
These containers are shown in this Field Manual dealing with airdrop of supplies and equipment (from page 159 onwards)

but as far as I can tell, there’s no specific designation mentioned
