Sci Fi Spell breaker

Level 4
Jun 5, 2012
What I am requesting is a version of the Spell Breaker that can fit in with a Space Marine Army. This can be a retexture or a new model. There are a few additional stipulations I would like to add:
1: Replace the glaive weapon with a grenade attack
2. Make the Shield Metal, and not some plasma energy shield like Halo's Jackals or the Gungans
3. Keep the Defend animations
4. Make sure the new model/texture is recognizably Human, not Elf.
