Watch Russian and Chinese marines invade the South China Sea together

The Russian and Chinese militaries set the news world buzzing last September when they conducted a bilateral exercise in the South China Sea that, among other things, saw hundreds of Marines conducting beach landings and air assaults to take over an island.

While the week-long exercise also featured anti-submarine warfare and other naval operations, most of the news coverage was of the Marines hitting the island. (In their defense, getting good footage of submarine battles is kinda tough).

Sure, pundits wrung their hands about the ramifications of a China and Russia conducting joint operations. But the fear may have been a bit overblown. After all, China participates in a lot of naval exercises with the U.S. as well.

The location and the activities in the exercise are important, though. Portions of the hotly contested South China Sea are claimed by a few nations, including the Philippines, China, Malaysia, Brunei, and Taiwan. If China were to try to edge other countries off their claims by force, this is the exact exercise they would need to do to get ready.

And the Chinese marines do look good in the video below, working with landing craft, tanks, and air assets to quickly take and hold the island alongside their Russian counterparts in green. See more footage of them in the full video from War Leaks below:
