US Marines in Thailand for the Cobra Gold training exercise took part in one of the wildest parts of the drills – drinking cobra blood. This was the 37th edition of the exercise. Cobra Gold is an annual military exercise for Marines and one of the largest in the Indo-Pacific region. This year, seven countries are participating in Cobra Gold – the US, Thailand, Indonesia, Japan, Malaysia, South Korea, and Singapore. Part of the drill involves jungle survival. Marines learn which plants and animals are safe to eat if they’re ever stranded.
