LOL, I'm trying to picture somebody jumping into a bacta tank in the middle of a fight.
As battle rages around him, Joe McStudly whips a huge bacta tank out of his back pocket. He throws it down, and climbs up to the top of it. As he opens the lid and jumps inside, he yells to his groupmates, "Hold on guys! I'll be out in a couple hours! Just hold 'em off until then!"
Lol, I just meant is reusable.
