What happens if it dies before it's owner uses the stratagem it gives? We D6'd it last game, but I'd like a consensus now. In the rules, it doesn't state "As long as the Damocles rhino is alive" or any such text. it just states that the player gets the stratagem.

The Assault Wave of
the Ancients DataSheet says that in addition to the normal stratagems your army also gets Flank March. It is not tied in anyway(other than
paying the points for it) to that Data Sheet, if you wanted to you could Deploy the Datasheet on the Table or Pod them all in, put them in a Thunderhawk
whatever you wanted to. Nowhere does it say they must also be a part of the Flank March. The wording on the Damocles says that the Damocles is what is
giving the Orbital Bombardment, so as I read it if it is dead IT is not giving anything anymore since it is not there. The way the wording is written
for the Damocles and Masters of the Chapter is different is simple, two different sources ForgeWorld and GW respectivly. To make it simple and quick at the
time Mike and I just D6ed it to speed things up, but no that we have time to discuss these things we might as well. To me any DataSheet that says X is giving Y
means that if a X is alive Y is able to happen, if X is dead Y can not happen by X.
