grenadiers

Every now and then I am reminded that Imperial Guard are only supposed to be good at one thing, and that's gunlines. There's really no way around it, Imperial Guard are at their best when in a giant line, and all firing their guns.
However, I always have tried to find ways around it, from using a few stormtroopers to using mass assaults, from ogryns to rough riders, I've tried em all.
Today we'll be focusing on Grenadiers. Now there are a few ways to go about using regular guardsmen and the best way is to use veterans with the grenadiers doctrine. Now these men are double the points of regular Guardsmen, therefore you can only take half as many, but with increased BS and increased armor, you have a unit that can assault fairly well, just remember that the more of these men the better, however, don't skimp out on them either, because a unit with three plasma guns is more than worth it's point cost when it comes to Space Marines anyway.
As far as using them, if your opponent is a gunline, then run up the table using straken to give a well timed move move move order or two, using cover as you go, and when you finally get there, if its another IG army, get the regular guardsmen first, they should fold like paper, ifnore the heavy weapons for now, they are surprisingly resilient in assault, and shouldn't be firing at you since your in close combat. pretty much follow what can fold like paper first, other than that, you might want to consider dodging the tougher enemy troops, as they are likely to kill your guardsmen pretty easily. In the end these men should be well supported by heavy tanks and or artillery, use those supports to kill the things that you know your guardsmen will have the most trouble assaulting.
