Changes the Shenlong name, cameo and description. Also makes it amphibious.
The Swimlong is a super heavy fishtank just recently deployed by the Chinese military as part of the effort to cut down on the number of soldiers required to pilot the massive tanks used by the PLA thereby allowing them to deploy more troops to their Pyro infantry divisions.
It is aesthetically identical to the original Shenlong except that it's entire crew, save the lone human communications officer, have been replaced by Chinese river dolphins.
They were originally planning to replace the entire crew with dolphins completely but due to the fact that dolphins cannot speak they decided to have a human translator/communications officer remain a part of the crew.
Since the tank is piloted by dolphins the entire crew compartment is filled with water so that the crew are able to move around. Being that Dolphins cannot breath water, and neither can humans for that matter, all members wear respirators which are conveniently connected to the large oxygen tanks that fuel the massive flamethrowers mounted on front of the tank's turret.
The Russians and Americans were quick to laugh off the new addition to the Chinese military before they realized just how dangerous a combination aquatic mammals and flamethrowers are.
