That makes perfect sense, as front-line weapons (1903 and 1917) were destined for the trenches and front lines. 

It's fascinating to me that the Krag... a rifle that most have (incorrectly) condemned to having had a short service life and second class citizenship behind the 03 and 17, has in actuality had a long and distinguished career - SAW; Philippine Insurrection; Boxer Rebellion; WW1 (rear echelon, limited use in action, and training); WWII (training); Use on U.S. Naval Vessels up to and beyond WWII; and use by State Guards, National Guard, and local militias.  This is all to say nothing of the tens of thousands of rifles sold to John Q. Public and used for hunting, defense, and (in the case of us CMP guys) use in Vintage Marksmanship Matches!

Yessireebob...  The Krag really was a relevant... and important US Rifle!  Thanks for sharing Knute1
