"EV" is long-life version of ordinary tube (5000 hrs). Star sign means OTK - quality control compliance (the same you can find on other products like milk and cheese).
"Military quality" is more a marketing term used today. Yes, military equipment mostly used "EV" and "ER" version of tubes whenever possible, but it doesn't mean "EV"/"ER" labeled tubes passed some special quality control at nearby rocket launch site targeting warheads toward your home town.
