I've solved the Ch-III #479 level. The key is to move the mirror
J5 to C9 and to kill the AT A9. The rest is easy.

In order to get to the flag, there must be things at B4 and B5 to prevent the LT from sliding on the ice. There are only 3 things that can possibly get there: the 2 blocks and the left facing anti-tank. In order to get by the conveyor, one either needs a block in the water at D9 or there must be something at C9. There are 4 things that can possibly get to C9: the 2 blocks, the left facing anti-tank, or the J5 mirror. The anti-tank would not do any good, since it would shoot. Using the mirror there would allow shooting the A9 anti-tank, so that is the approach I used. I shot the A9 anti-tank before I got things to B4 and B5 because I needed the LT to get to B4. In my solution, I moved everything that is movable. The effort was figuring out what order to move things and what paths they should take to get to their final destinations. My score for the level is 573/45, which is not even close to the GHS of 297/37. So it looks like there is a solution with major differences than my solution.
