Can you self TAG for SG-LRMs?
I can't really decide on this match up. With Stealth up both have the same heat capacity for movement and weapons. The Owens has a ton more armor, and can walk backwards nearly as fast as the Raven can run at it. As others have pointed out the Stealth Armor means you need to attack from medium range or closer. However 'close' is seven hexes for the LRMs, which is medium to long for the Raven's weapons, and he'll have to drop one laser out every two to three turns to cool down.
Working with the Owens it'd be soften him at range if you can, then once your LRM ammo is exhausted go in for the knife fight. You have enough of a speed advantage that he can't keep away long, not that he wants too.
The Raven wants to keep his stealth up while the LRMs are in play, and try to NARC the Owens. Go half beacons and half explosive warheads on the ammo. Once the LRMs are down, drop the Stealth and hope your heavier firepower can punch through his thicker armor first, you can hit twice as hard in close.
