Ruslan is not completely happy to see that it's Cody who comes out. Cody is indeed the one who can possibly take down the shielder the quickest, but that means Ruslan will go with the rest of the team in the counterattack following the neutralization of the shield. That is a problem for him, not because he doesn't want to do it, but because he's not in the tunnel and is suffering difficulty coming back inside due to the suppression fire. Hence, he doesn't know the team's plans right now.
