Would I have a case

Ok I was at work at a military store on a military base. I was on the clock And I sometimes have to Back trucks to our loading dock. There is no extra space In the doorway to signal the driver once he''s within the last couple feet. So here I was backing this truck in and I had him Stop but then realized that he was not close enough, now keep in mind These trucks don''t have ramps or cameras or Extra mirrors to prevent having to do this. I had to lean my head out The side of this doorway to tell this driver to come back, just as I stuck my head out He back up about 2 or 3 inches catching and pinning my head between the back of The truck and the concrete wall almost crushing my head. I was stuck pinned for about 30 Seconds yelling for my life for the driver to pull forward and he finally realized it, pulled forward and I got my head free and was flown by plane to a hospital. I had no real damage but the principle of the matter these trucks need to be made with cameras or mirrors or even putting ramps on them. It is unsafe and I nearly lost my life. I would like To know if I would have any case against anyone. If it''s not me it will be someone else who is not so lucky.
