I like the addition of the Silver Star, Starfleet/KDF Cross and the Medal of Honor. There are two medals that were overlooked and that I believe should be added: The Bronze Star, and the Leigon of Merit.
I would reccomend that The Bronze Star be earned for completeling 25 of ANY STFs. Likewise the Leigon of Merit should be given for 50 STF completions.
I felt that starting at Silver Star glaringly overlooked the Bronze Star. My suggestion easily corrects this.
