Welcome to Librarium Online!
I for one run a very mechanized list with lots of rhinos. I love them. They keep your troops alive. They are rolling 4+cover saves, and recently I have gotten into the habit of tank shocking weaker low moral troops (today I got like twenty Gaunts to run off the table edge with just using my rhino.)
My question is do you run with or think it is a viable option to equip rhino with Doom sirens to give you even more of tank shocking action?
Don't you mean Dirgecasters?
No, I don't think -1 Ld to Tank Shocks is worth the points. There's not exactly a shortage of Ld 10 enemies, not to mention Fearless ones.
Don't get me wrong; I've turned games around with my Rhinos...
But its not something to count on.

Hmm...I've never had anyone use doomsirens against me before. Although I've fought Dark Eldar and their loads of morale breaking toys. I'd say throw one on a rhino in a game and catch your opponent off guard. Worth a shot. What's the worst that can happen in the end, if my marines had an option like that I'm sure I'd utilize once or twice as I tend to tank shock a lot.
