The square with hawk in the middle carved into the stock is the patch of the 45th Inf Div. The 45th an Oklahoma NG Division, fought in Sicily and Italyin WW2. They also fought in Korea. This may be where the 45th Div comes into play as Ethiopian Kagnew Guards, the cream of the Army fought in Korea. Looking up the division affiliations of the Ethiopian soldiers were mostly 7th Div, but it is entirely possible that the small unit could have been involved with the 45th at the closing months of the Korean conflict. Since the Korean war was a UN conflict, it is also entirely possible that a unit of UN troops were involved in the Philippines. The Philippines signed the original charter of the UN in 1942.
