A military ship like the Polaris should come stocked with supplies like MRE's
The Pisces comes with med pens, some food and water.
The Redeemer has a whole food bar(which usually gets dumped on the floor mid flight).
The Corsair gets a hidden flask.
The Polaris a military ship should come stocked with MRE's, some drinks and medical gear in the med bay as well. Nothing more military than opening up conserved rations from pouches.
