I've talked about my breachers and how great I think they are however they have a glaringly obvious weakness in the fact that they are slow (and more so when using the Stone Gauntlet if I don't want them to lose their bonus). When playing the Stone Gauntlet, I like to have a rapid response squad to either support my slower moving breachers when charged by an enemy unit or to advance on a distant objective otherwise out of the reach of my breacher squads.
Sometimes I use veteran tactical squads in Rhino APCs for this purpose but I find assault marines are great for this role.
Bikes could also fill this role but I like the fact than my assault squad could be used to charge in and finish off a combat that is otherwise tying down my breachers. Power weapon options allow me to more effectively take on terminator armoured squads for instance (instead of purely relying on volume of attacks). They are also useful as a counter assault unit if you really want to slow down or otherwise stop that huge tactical unit from approaching your lines.
What do you guys think? Do you make use of other squads for this kind of role on the battlefield?
Until next time!
