The CSM was one of four people that received the silver star during the Haditha battle. If I remember correctly, the CO and 1SG from B. Co. 3/75 did also, but I cannot remember the fourth. With the exception of the ol' 1SG, I haven't heard from any of these guys in a long long time, and I'm not inclined to pass along names without getting their permission first. Please don't ask.
Just a brief summary of the battle, the main assault was conducted on April 1 by two platoons from B Co and one from C Co, 3/75. The CSM traveled with the assault element. I'm not sure how long the "sniper" part of his participation lasted, but unit lore is that his spotter was a young ranger that got stuck lugging around a CLU after all of the tubes had been spent. The rangers captured both the 16-story hydro electric facility as well as the little village on the first day. The object was then held against counter-attacks for 9 days until armor could make it there to secure it for good. During the raid other elements from 3/75 secured strategic points in the near vicinity. It was at one of these blocking points that the only Ranger KIA's during the entire battle occurred; SSG Nino Livaudais, SPC Ryan Long, and CPT Russell Rippetoe, all of A Co. 3/75. (
