Today's Hobby Update features two units of Inceptors for my White Scars army. I recently started adding these units to my White Scars tournament list.
I find the firepower and mobility of the squads to be quite useful in my games. I normally bring them on in turn 2, where the Tactical Doctrine means their Assault Bolters are at AP-2. Keeping them in reserve also keeps them free from enemy firepower for the first turn.
