Yeah it's a do it all weapon, that's why I laugh at it. giving such weapons in the hands of expendible guardsmen is a waste of ressources.
Yeah I forgot how in Aliens bit was failed due to a weak, inexperienced commander and crappy intel first, rather than cowardly soldiers. And guardsmen are never gonna be send agaisnt Tyranids? Must be why they talk about it in the Uplifting primer- must be why it's all false information as well "No need to give them real xeno knowledge- Those are for Astartes after all!"
Yeah, rather be tolling away in some factorium instead of standing guard at the Spire with 3 squares/day.
