Snow Serpents are Cobra's . They have a reputation for being formidable fighters in sub-zero temperature conditions. However, all that meanness didn't come out of nowhere. They are a branch from the ranks of the Eels. As such, they have undergone the same extreme aquatic training and, in addition to that, they are trained to be well-versed or familiar in every possible type of infantry operation in an extreme environment such as the Arctic. From marching 50 miles with full gear to anti-tank tactics to airborne operations, they have to be able to do it all.
