I've just finished painting a detachment that has caused my opponents to rage quit. My new favorite Warhammer 40k detachment is a Spearhead of Astra Militarum (nay Imperial Guard) Manticores with a Master of Ordnance from the Catachan regiment. Defending my kitchen counter top, not a jungle. These guys pump out 2d6 shots of S10 AV -2 carnage. Making them Catachan allows me to re-roll one of the random d6 shots per missile used. Keeping my master of ordnance within 6" of the tanks allows me to reroll 1s to hit. Needless to say, they rain hell on my opponents and there isn't much they can do to stop it. How do? Got Mortarion? Turned to dust. Got Magnus? I don't even have to see you. Got giant bugs? Exterminated. At less than 500 points, I have a hard time finding another formation that can pump this amount of damage that has rules that buff itself as efficiently without spending any command points. It's great against hoards, monsters, Primarch
