Hi Mrg, please avoid such sentences as "I suggest it is simply your attempt to nationalise the article to reflect some sense of patriotic pride in his achievement, but this is not the place to show it." They go against WP:AGF. I can start simply assuming as well about your intentions but such things are not helpful at all to discussion.

This is a very simple non-issue. Bagramyan enlisted into the DRA army and fought within its ranks in very crucial (and famous to Armenians) battles against the invading Turks. When you join an army, you are going to fight by its side which Bagramyan did, especially during that time when the Turks were a few km away from Yerevan. The battles (especially Sardarabad) were battles that would determine life or death of the newly established republic. What he joined, became or did after or during the fall of the DRA has nothing to do with what he did prior to it. The DRA's "brief experience of independence" does not disqualify Bagramyan's service to the country and to its survival.
 
Also, "Unless you can provide factual information that he was a commissioned officer in the DROA, I would have to assume that he supported Communism, or at least Socialism". Don't forget that the DRA was ruled by socialists who were majority in government by far and also held all important posts. -
