Wouldn’t it be cool if research had a mobile lab to conduct experiments, gather materials, and perform research in hazardous conditions? It could be purchased through intel or otherwise usable from the vehicle bay. By default it should contain the essentials of the research lab, maybe a row of hazmat suits, a containment unit (possibly for live capture of dangerous specimens or substances), and a storage unit for bulk collection of research grants, vials, photos, etc.
I think this would mostly be an RP hook to get researchers onto the field in an interesting way. The field lab should be modestly armored and unarmed, requiring a marine escort in combat situations. Zombie rounds in particular would be a special use case of the mobile lab, capturing and studying zombies for onsite creation of a cure.
the MPs might also share joint custody of the mobile lab for forensic investigations, if a heinous crime was committed in the field that needs an actual mobile lab to investigate.
