You do have some influence in where you get posted, but that is mediated by several factors including most importantly how desirable a posting is. While I'm not certain of how desirable an Arctic posting is, I do know that Antarctic postings are heavily oversubscribed (more demand than spots available), and I rather suspect that the Arctic stuff is in the same boat. It's not like there's a huge amount of spots that need to be filled, so even if getting an "Arctic soldier" tab appeals to only like 1% of the soldiers, well, that's enough to fill all the slots.
