Someone needs to escplain something at me

Yused to watch this show when I could back in the day. But nevar caught all of the eps. So may be misrembering something, but could sware I saw an ep wherr Major got killed, IIRC she was abote to get on a plane and a sniper blew moast of her brains out. Batto, the big guy with the cyborge eyes that had a crush on her, was real upset.

So was that real, or an alternate artificial realty? Was that the end of the show, or did Major get dowloaded from a backup into a new ghost shell, or what? If that wasno the end, where did the end happen? Was a clean exit, or djust stopped without wrapup?
