I also like your title and how it fits visually and symbolically. For those that don't know, cold steel, in addition to physically being cold from the weather, is also referring to the bayonet.
A book I was reading for a military history class in the Korean war was describing CAPT Lewis Millett (CO, E Co, 27th Infantry Regiment, 25th Infantry Division) and his leading a bayonet charge against the Chinese near the end of January of 1951. The only reason he and his unit were not wiped out was because the Chinese defending on the hill continued to toss grenades instead of firing their weapons. Millett ended up being awarded the Medal of Honor. Interestingly, a Captain Reginald R. Desiderio also received the Medal of Honor. He was CO of E Co, 27th Inf. Two COs of the same company receiving the Medal of Honor is a rare thing indeed.
Sorry for the anecdote. You figure and dio is well done and much deserving of appreciation. A worthy entry.
