That is actually an official erratum. It was clarified in the Q&A question of one TTD (Or MTJ? I forget...) that you still
can have mixed turrets.
I have been working on a unified combat&damage system for MT which replaces both the point-based damage for personal and vehicle combat and the HG-based space combat with a roll on the mishap table, modified by weapon penetration, target armor and target size. I would probably still use special rules for space combat (but with the same principles, and seamless integration with the other rules) because of scale considerations.
Unarmed combat or light blunt weapons: 1d mishap
Projectiles, laser weapons, blade weapons, heavy blunt weapons: 2d mishap
Energy weapons and explosive rounds: 3d mishap.
The mishap level is reduced by 1d for hard targets (vehicles, robots.)
Modifiers: +pen, - armor. Max. net modifier +/-8
Special modifier after damage: Target size.

For starship combat, I'd use HG armor values and accordingly modified pen values for the weapons. Size VSmall would correspond to size "Giant" under the personal rules (Yeah, I should unify these, but I am bad at coming up with English synonyms for "Larger", "Even Larger", "Still larger", "Keep going" etc.)
A SUPERFICIAL mishap corresponds to cosmetic, non-function-impairing damage. A flesh wound for living beings, small hull damage for vehicles, robots and starships.
A MINOR mishap corresponds to partial damage to important systems or heavy damage to unimportant ones. A living being is hampered (negative DM) and may drop unconscious from more than one MINOR result. For vehicles or starships, a randomly rolled system hit (ad-libbed, or one could use the table from MT.)
A MAJOR mishap means that important systems cease to function. Living beings drop unconscious, and can be killed by an additional MAJOR result. Vehicles are stopped/shot down. Starships suffer the equivalent of a critical hit.
A DESTROYED mishap means complete failure of functions. All important systems cease to work. Might still be salvageable.
A TOTALLY DESTROYED* mishap means just that. The target is utterly destroyed. All systems are destroyed as well and cannot be repaired.
*19+ under my rules, only possible with DMs.
This system is naturally not yet completely worked out, but I plan on expanding it and eventually writing it down in readable form. I realize I have somwhat strayed from the original topic, but do you have any thoughts on it?
