Snail is technically correct, however the 'HTL' Legion shouldn't be considered the de-facto standard by any means. It's got many flaws, not least of which is the fact that the hole is all but a cylinder (cylindrically tile mapped at that) booleaned out of the side of the ship. It's also based off of a radically different base HTL model than is used in the Media VPs, so it will look out of place as much or more so than the original low-poly one unless you're going with an all-Trashman model set. Venom's Legion is so much better - it's more detailed for its polycount, and it's got custom textures that give it the appearance of an abandoned, burnt-out hulk that Boolean-Subtract just cannot ever convey.
