None taken, Pippa, it was an interesting question. Hand signals also help if gunfire makes you temporarily deaf. There are earplugs that let you hear and close suddenly at supersonic sounds. There are earphones that do the same when sound goes over a certain level...some even have radios in them. Good for working around noisy equipment.
Being able to hear very slight noises can be a life saver. You can hear insects walk in the woods at night. Hearing someone move on the other side of a wall or the click of a trap activating can save your squad's life. That's why they demand good hearing.......then they put you in the artillery and destroy it.
Well, I don't like what they did to me but it's nice to know Wendy can take care of herself. I swing a mean purse.
