Fyi:
The maneuver I referred can be found in Run&Gun p.125:
RUN FOR YOUR LIFE/ DIVE ON THE GRENADE
Interrupt Action (–5 Initiative Score)
There are few things as frightening as the distinctive sound of a grenade bouncing into your vicinity or watching a swirling ball of mana headed your way and set to go boom. By the time you realize a whole lot of trouble is on the way, there are very few options available. This action covers two of those options. There is a third, far more dangerous, option for incoming grenades
covered by the Right Back At Ya! Action. Immediately after a Throwing Weapons Attack or Area-Effect Indirect Combat Spell Spellcasting Test, a character can make an immediate Interrupt Action to flee. The character chooses a direction to move and can use any amount of available Movement to move away from the incoming attack. (Note that the gamemaster is not obligated to determine or declare the final location of the attack in the case of a fleeing character. A bad bounce can still get a grenade on the character’s tail.) In the case of diving on the grenade, the character moves toward the grenade, still limited by available remaining Movement, and can choose to make a Drop Prone Free Action when reaching the grenade. The sacrifice
means the character takes all the grenade damage and eliminates the blast. In the case of a gas grenade, this action cuts the effective radius in half.
