I recently started a campaign and have a Space Wolf Tactical Marine who would like to get a bit closer to the fluff. He wants to be able to get stuck in with bolt pistol and close combat weapon when the melee closes with him. He doesn't wish to do the Assault Marine's job so much as be a propert Grey Hunter. although he has the Two Weapon Talents available, they're at Rank and 7. He wants to be able to be better at close combat soonish.
Now my understanding is that if he attempts to dual wield a pistol and a close combat weapon, he will be at a -10 for both due to not having the two talents. Are there alternatives that he can take at Rank 4 or sooner?
