Erus thats why its called the chewbacca defense. instead of useing lawyer jargon to get a jury to do the right thing you simply bombard them with useless and nonsense information to persuade them to either give up or agree in some crazy way.
my post had just as much to do about anything as erus talking about a skate boarder hitting a parked car.
now point for point a space marine is better then a guardsmen. theres no arguing with that.
however when you try to declare a sentinel as a tank you are stepping over the line when even the most basic of space marine weapons can destroy it. then again when if you even hit one of his men with a bolter round its instant death as they dont have an armour save with out carapace (even then im not sure)
but as we have all said guard suck in small point games unless they are packing tons of conscripts and a commissar as far as i can tell.
meet him in a big game where he can bring in the big guns and most of the time the guard will wipe the floor with the astartes.
that is unless your using the space marine movie list.
also chaplains are just monsters in cc. probably not his best choice to let you get close
