@Hanith: While I respect your decision to self-limit yourself regarding use of DT in game play, I think we need to be careful about assuming RAI, especially since not everyone agrees with your thinking on this (myself included).
Stepping briefly into the tactics realm: I know of several SM examples where DT is taken but deployed empty. One is an 'empty' DP dropped on a far objective from reserve late-game to contest it (often C&C games), without wanting to suicide an infantry unit within it or losing their ability to shoot from the 1st turn. Another is to take a LR as DT for termies, then deploy them separately during the deployment phase. This is a good way to get a LR Achilles or other LR variant onto the table without using up a HS slot. I like to deploy an Achilles right beside a small scout squad, which then embark and go park on an objective. Some say cheese, some say good tactics.
