starfleet marines new weapons and uniform
Personal shielding in the show is pretty easy technological. But to see it in action will be to much time consuming. Remeber it must show not only when it gets hit by enemy fire, but also when there is water, rain, when the person hits the ground. After running for cover. Etc. The shielding will make much more sense with power armor or simple All enviroment armor.
I sure hope they have some kind of personal shielding device, I always wonder why they don't do that in the show. It should be pretty easy technologically.
