For one, the Turks didn't change their uniforms that significantly, and secondly, who cares what weapons the characters used? For as far as we know, they could've discovered new weapons by the time the movie took place. That detail was so minute that it was completely insignificant. However, I feel that Cait Sith riding Red XIII was far from a little detail. It couldn't have taken them too long to explain and it would've cleared up alot of the confusion.
