Team Leader - New Lieutenant
Team Leader and backup to the science officer
That was not in the manual
Walter is fresh from OCS. He is a large bear of a man with a soft voice and a preference for books over violence. Not that he is opposed to violence, as long as it gets directed at the bugs.
Walter and his team weren’t so much chosen as they happened to be in the right place at the wrong time. His love of science is just a bonus and assured him of being the leader.
