New turret model :3. Can be either thunder tower, lightning tower or a tesla tower (but I choose thunder tower because it sounds cool even though idk what it really is XD).
-I recommend to give it a lightning attack ability with the projectile launch Z of 200.
-The metalchunk files should be in its default war3mapimported path as it should be when you import it :^.
Just a note on the English language (since you said you're not sure what it means):
Thunder = the sound that you hear during a storm when lightning strikes the earth.
Lightning = the electricity and flash of light that arcs through the air during a storm.
Tesla = a Serbian-American inventor famous for his experiments with electricity (though you probably knew that one!).
