Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Inner ear causes of vertigo most commonly include benign positional vertigo (BPPV), such as what you mentioned, which is due to small particle in the inner ear that moves out of place, and can be repositioned with simple head maneuvers. The symptoms often include vertigo that occurs with turning of the head, often while turning over in bed. Another cause of vertigo that may be associated with tinnitus (ear ringing) and hearing loss is called Meniere’s disease and can be treated with medications and sometimes surgery. Other causes of vertigo can be headaches, demyelinating disease, thyroid dysfunction, atherosclerosis of the posterior intracranial arteries, etc.
Vertigo can be triggered by many things. Loud noises being one of them. Since you are deployed, I would suggest you ensure that you protect your ears with a protective device.
You should be seen by a neurologist or ENT when you return from deployment.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
