Concerning the controversy with the ruling on Grenades in Assault, I was thinking on how to compromise the positions. I thought, "
set it up to where only models base to base with the Vehicle may use Kraks/Melta Bombs, etc. Anyone further back would be throwing it!"
Refining it a little, I came up with the following, changes in green.
Some grenades can be used to make shooting attacks or attacks in the Fight sub-phase, albeit to different effect. Only one grenade (of any type) can be thrown as a Shooting Attack by a unit per phase. Models in base contact may plant a Grenade (one type per unit) as a Melee Attack if it is a valid target.
Errata Krak, Plasma, Haywire, Melta Bombs, and similar Grenades Assault section to use the verb plant with their Assault sections.
