Send your scouts out with small cover arcs so they don't fire on anything they spot. You should be able to spot some heavy weapons down near the cross roads. Nail them with direct fire from your mortars.
Then set up a base of fire in the center hedgerow near your starting positions. Be mindful of kraut mortars and keep your guys spread out. If you notice any spotting rounds bug out asap. If you managed to KO the AT gun with the mortars you can park your tanks behind the same hedgerow with impunity.
Next clear out the farm, first pump some HE into the buildings with your tanks, the krauts will break and run if they know whats good for them. Move a squad or two across the bridge, if you're feeling crafty lay some 75mm smoke with your tanks to cover the assault. Use assault command with your squads or split them up. The idea is to keep two teams in a position to fire on any krauts that poke their heads up while the third team moves.
If the battle isn't won by now you have to clear out the bocage on the right flank. The krauts like to set up machine guns in the corners so first step is to suppress them with HE from the tanks (or mask them with smoke), along with the entire hedgerow base. If you've got any mortars left drop them behind the hedgerow you are attacking. With the hedgerow taking a thorough hosing (or screened with smoke) move your rifle platoon one square adjacent the hedgerow (so that they CANT see through to the other side) and lob grenades over, then move up to the hedgerow. Lather, rinse, repeat until you reach the crossroads.
Another trick is to set up your machine guns in the top floor of the farm buildings. From there they can put some enfilade fire into the bocage.
