Um...battle them?
Beat the grunts
In Pokemon Platinum, the player has to defeat several Galactic Grunts and Commander Saturn to get them to leave Lake Valor. This happens after Team Galactic uses a bomb to dry up the lake.

after defeating commander Saturn at Lake Valour, you have to go to Lake Verity, fight four galactic grunts and then commander Mars.
In the Valor Lakefront.
First, you need to talk to the Professor in Canalave City, and he tells you to go to Valor Lakefront because there was a boom. After you defeat the Commander, the Grunts will be there. Then, you get the Snowpoint Badge and one of the Grunts will be moved to the side and you can pass through. ~Lucario
