Frag dreadnought & overwatch

[CastellanDeMolay]

RAW: If a Template weapon fires overwatch it automatically inflicts D3 hits. 

This bypasses the normal rules for firing a template weapon, so modifiers like the number of shots don't come into play. 

 

GrunTeufel, An overwatch attack is resolved like a normal shooting attack, and under normal circumstances a Walker that moved can still fire all of its weapons in the shooting phase, so, without any explicit restriction on how many of a Walkers weapons with which it can fire overwatch, it follows that a Walker can fire overwatch with all of its weapons.

I play 2d3 for the Frag Cannon, and 1d3 for the heavy flamer for 3d3.  No one ever gripes about it.  2d3 makes sense if it shoots twice anyways.
