when it comes to submarines, the illagers were the masters of them, when the illagers were united, they form a submarine division and build their first sub, the u-1, she was lost in a river. the first illager series of U-boats is the small coastal ones, but were quickly disposed of due to their small size, the second series were more bigger than their small parents, dive deeper, and live longer underwater, a submariner's uniform is the same as the illager sailor but uses a blue shirt rather than a white shirt, the submarines and the submariners were used heavily on every front mainly because the illager navy wasn't t varied enough, when the second series were getting more and more successes, the exiled republicans deployed their minelaying submarines into action, the illagers decided to do the same, their minelaying submarine did somewhat successes, while ding their jobs at minelayers, they can't hunt the warships down like the second series, when it comes to dimensional waters, the third series could work, they were longer, more faster, have better range, dive deeper, and can survive longer in water, but lost it's bulges, they didn't do good, mainly because of the bulges, but did successful against the great allies, but the advantage of the submarines were declining because the great allies were using q ships, depth charge, and mines, the fourth series were gonna make the great allies surrender and wet their pants, they were well built, more powerful, more stable, and many more, but only a few were many, when the great war was over, the illagers made 8,640 u boats, the u boats were handed over to the great allies to be scuttled or scrapped so that no one could have them, the only u boat the illagers made to remember they used to rule the waves is u1.
