This isn't Woodsmen of the World.  This is firefighter related or military. Woodsmen of the World do not use insignia like this nor do they use dubble axes like what is on this badge. Nor do they use numbers or letters. I don't know why people are so confident about something when they either dont know for certain.

No, not US Army Pioneer Infantry. Woodmen of the World is the closest, I think.

Closest item that I could find was this, sorry I couldn’t be of more help.   https://www.ebay.com.sg/itm/226153707377

Nice finds! I really like the medal grouping.

Sweet!

Robert Tucker at a military base October 18, 2005 in Dujail, Iraq. Tucker, 20, from Cookeville, Tennessee, was killed by insurgents when a roadside bomb blew up his armored vehicle on October 13 near Dujail, just two weeks before the end of his 10-month deployment in Iraq. He was assigned to K-Troop, of the 278th Armored Cavalry Regiment, which patrols the area around Dujail. Saddam Hussein is scheduled to go on trial on October 19, for the death of 143 people from Dujail who he allegedly ordered killed in 1985 in revenge for an assassination attempt.

Got this last year at a thrift store. Not sure if it was ever used though.

Thanks guys. I guess finding a 123rd with a K will be near impossible. I'm glad a simple crossed rifles and US would suffice.

Sorry that the images are blurry, I did the best I could.
