nah. The plasma weapon was the Roms. Not very good engineering, though: they could run or shoot, but not both simultaneously.
Still, it was a cool weapon because in one instance it gave Rico-Suave Kirk an opportunity to hug Yeoman Rand. Yowza!

I believe a more correct name would be Yeoman Janice, and yep, she was a looker back in the day. Kirk always got the girl..
