False sir,
Navy Reserve Merchant Marine Warfare Badge was first authorized in 1915...granted they took it away from us a few years ago and replaced it with something lame..
HA HA! Wait, your serious?
After doing a little Googling the assertion seems a little thin, with only some sort of insignia to be worn back in 1913 with no pics of what it was. The 'chicken' that was current until 2011 wasn't created until the late 30's. So to call it the oldest 'warfare pin' is a stretch to say the least. Not only that but the original appears to be less a 'qualification' than an insignia for merchant mariners in Navy service. It all sounds like some great propaganda on the part of the maritime schools, they seem to have taken a lesson in that from the Marines.
So, not so much.
