"...btween the original and the request, the boilerplate language changed...."
So then can we look at someone else's Silver Star citation issued at or around this time and see if this is, in fact, just boilerplate?
Yes. That is exactly my thought. Look at Silver Star citations issued in the same timeframe as the one signed by Lehman, and see the language in them, particularly the concluding sentences.
