As a tech marine the ability to use and improve cover with your own ability and the evaluate skill is important. I have been carrying arround metal doors, pices of wall, and in one case a car sized vehicle to basically use as a shield in fire fights.
In D&D and Pathfinder there is something called a tower shield that is so big it behaves as cover. I was wondering if there was something in warhammer 40k that I could requisition that is similar, insted of having to constantly find things to improv with. This would also add an elliment of balance as it would mean that I have to pay some of my requisition to gain the armor advantage.
Note I am aware of the existing power shields equiped with force fields, but I am looking for something more primitive, and that I can improve using the cover rules.
