Another LRM support 'mech. Quick enough to stay in the middle of the group and fast enough to get out of trouble.
I've always wondered what an LRM SHD would look like. I think moving the ammo around to limit the chance of a Ammo loss is a good idea, with this many missiles.
You could save 1 ton by replacing that CT LRM10 with two 5-size launchers (CT + Head). Additionally, the XL280 weighs the same as your XL275 (which probably came from your SHD-5M?), so there's a small amount of improvement available as well. I replaced that LRM10 and changed the engine. The weight saved went into another DHS in my proposal, but feel free to use it for something else. Another possibility would be to lower the engine size. Fit an XL255 and mount an additional BAP would be possible then. Or an AMS if you prefer that one. On a sidenote, I am currently playing my 2D2 with an XL255, quad LRM5 and 2 ERLLas. Very funny build.
