I found yours of 4/2/04 while going through some past postings. The "shoulder cord" referred to is the "Fourragere in the colors of the Croix de Guerre of France," commonly called the French Fourragere.
67th AAA Battalion, originally constituted as 1st Battalion, 67th Coast Artillery in 1918 was, in fact, deployed in Italy during the war. The battalion received one award of the Croix de Guerre with Palm, represented by a streamer emboidered "Road to Rome" which may be displayed on the battalion standard. Individual members, however, aren't authorized to wear anything to represent the award.
The Fourragere, a unit award, is authorized to be worn by members of a unit to signify that the unit has been cited at least twice in the Orders of the Day of the French Army, two separate citations for two separate actions. Individuals who participated in both qualifying actions are authorized to wear the Fourragere as a permanent part of their uniform.
Individuals who participated in only one qualifying action or who have joined the cited unit subsequent to both qualifying actions, may wear the award ONLY WHILE ASSIGNED TO THE CITED UNIT.
In the case of the 67th, inasmuch as there was only one citation and no award of the Fourragere, no one would be entitled to wear anything to represent the award.
Unfortunately, many - if not most - of those who post on these 'boards are novices, who, however well-meaning, have little or no experience in applying the methods or solutions they suggest. Caveat Emptor.
