Yep, a five-episode anime series with English dubbing has been available for some time now, you should be able to pick it up fairly cheaply from Amazon. Wikipedia also has a page on it, if you want to check it out before parting with your cash.
Its actually based on a trilogy of books from the author Chōhei Kambayashi, which are surprisingly thought-provoking and readable for military science-fiction. The third book has yet to be translated into English though. There was talk about five years ago of Tom Cruise adapting it to the big screen but that seems to have fallen by the wayside, a pity because like or loath him he does very good science-fiction movies.
On a side-note as fun as the anime is I kept wanting to give the main character a good shake, he’s a lot more lively and likable in the books.
