OK, thanks, just wanted to make sure the HEAT value present for Satchel charges and flamethrowers does not have an effect.
So if I wanted to downgrade infantry assault success, I could either give them HE "antitank" weapons (resulting in a significant downgrading, but as long as the HE pen is larger than that of a hand grenade, it would still be better) or HEAT grenades with lower penetration (which will result in less significant downgrading).
It's what I suspected, but since tests were not all that conclusive (as I forgot to alter "test infantry" morale and the buggers often failed to assault and panicked instead) so I thought I'd rather ask
