The Red Tape mission is straightforward and can be completed simply by following the objective marker. Nevertheless, it can be made much easier if you enlist PAM, the robot, whom you encounter as soon as you enter the facility. Having Parvati as a companion, with her engineering ability, will ensure you can enlist PAM. PAM will lead you through the convoluted route in the facility to the final elevator. PAM also assists greatly in eliminating hostiles. Her combat capabilities are similar to those of your companion, SAM. Although PAM makes the mission easier, you do not need her. You can follow the objective marker and eliminate the hostiles yourself.
