"I'll start by explaining the immortality. We have effective brain scanning that allows us to duplicate consciousnesses: however, this destroys the original brain in the process. My capsule is programmed to immediately do this process to me if it's breached, then transmit my brain state via ansible to the facility where my medical clone line is kept. Rather than dying, as would be inevitable if my capsule was breached in a combat situation, I wake up disoriented in a new body."
