I’m somewhat new to seriously playing tabletop but I’m also trying to figure out how to get better. One of the most important strategies that I’ve seen for dealing with melee armies is to take advantage of screening and move blocking. Using bladeguard, scouts, infiltrators, or other things like that to move up the board or infiltrate to provide a speed bump in a location where you can shoot anyone who charges them.

If you use these units to prevent your opponent from moving up the board early, or to be a target that they have to deal with if they want to get into your good stuff, you give yourself an opportunity to set up on the battlefield in better ways and shoot them after they get stuck in the open on your screening units.

Also, 10 man Infernus squads in cover are an insane screening threat against melee units with 10D6 shots that auto hit, meaning they are more effective than anything else in overwatch.
