Doesn't matter. You can get struck by lightning if you are wearing metal, or if you aren't. Just make sure your not standing at the top of a hill. ;) haha. That will lower u'r chances of getting hit. :)
Got struck by lightning in the Military was a Combat Signaler, out in the field. Running my longest antennae 15 ft high for long range signals, pretty routine. Heavy rain occurred / loud thunder / struck - flow up & back 15 feet away like a giant hand scooped me threw back. Couldn't move for 15 to 30 minutes - Lost track of time - was conscious with eyes opened could see everything. Water was flowing in & around my mouth - it felt good. Good thing i was on my side, not on my back or face - would have choked or drown. Except Frozen couldn't move anything like a flesh statue, couldn't feel anything either - numb. Slowly gained sensation & stood up, there were no burns or anything. Never reported it, everything was normal. What happened was covered in sheath was water almost like a cocoon from the heavy downpour. There are different kinds of Lightning - sky lightning & ground lightning. I got hit by charge from the ground going up into the air - as opposed from the sky. The other situation is that the downpour was so heavy that water flow all over me, which conducted the electrical charge over my body. But enough went through my body to freeze & lock my muscles. The Army wouldn't have cared my equipment was still operational, which was the Military main criteria. My days were filled with all kinds of Standing & Operational Orders that i didn't want to add to more paperwork & reports on top of all my reports & more other paper duties. Everything SOP. Meow
