I've already submitted a story about how I've experienced things my whole life. I didn't go into a lot of detail about all of my experiences and only listed off some of the more interesting ones. And I still experience these things and have a lot of stories to tell, but I will give one that I have experienced recently here at my first duty station.
I am an Airman in the United States Air Force Security Forces: a military cop. At the base where I am stationed (for security reasons, I will not mention where or what the base is called), we have a flight line smack in the middle of the base and because of some of our more important resources, on top of security cameras and sensors, we also have people posted along the fence line every 1,000 feet.
One of these posts, which is a large sitting on a dirt road beside the fence line, is what we call the most haunted shack. I'm not the only one who's experienced things there. I have seen shadow creatures and faces in the windows. A young Airman, male, hangs around there all the time, and I believe it's because maybe even after he's passed, he still has a sense of duty and feels he needs to remain at his post.
A few yards down the road from the shack, there is another, smaller shack that can barely fit two people in. It was the original post before it was moved into the larger shack. The last Airman posted there was said to have ate his own gun on his very first day of duty. There are two cement blockades sitting in the grass behind the small shack in a V-shape, as a barrier in case something goes down. And the history is that this Airman just walked out and sat in the V, put his M4 in his mouth and pulled the trigger. He's still there to this day.
I have been posted in the new, larger shack and I have seen a figure of an Airman standing in the empty shack. Even though it is faded and hard to see, if you pay attention you can see his shape. It looks like he's wearing the uniform and all of the required gear, along with the Security Forces beret on top of his head, and you can even see the shape of his M4 rifle that he was posted with.
Sometimes the door to that shack slowly opens as if someone is entering, or coming out, then shuts again all the way and locks. I have gone over to check on the shack after an occurrence like this because it is within my post limits, and I have checked the door and found that it was shut all the way and even bolted. And there wasn't any wind. It was a hot humid day without any wind to help cool down. I've been posted there many times and I see him from time to time.
