I don't know what you call it, but I'm thinking of calling it "the shredder", or something to that effect. I refer to the XV8 loadout of TL Burst Cannons and a third burst cannon, and I find that it is amazing.
A squad of 3 can put out 24 shots (12 of them TL, though I'd recommend giving one mode a TL melta and/or missile launcher for anti-vehix capabilities), add that with Shadowsun or an XV8-02 commander with a C&C Node or Sensor Suite, or even place them by a sensor tower, and you've got one of the shootiest low point cost units I have ever seen...
Yes, it's only S5 AP5, but honestly for the amount of shot put on target, TL + Markerlights could make even terminators fail a couple rolls per turn, then jump out of the way with the 'Ghost walks among" us trait. I just got some shivers thinking about it.
What's your favorite loadout, or what have you found out to be effective?
