The "A" suffix on U.S. 7 and 9 pin miniature types indicates controlled heater warm up time, for series string service. The character that indicates milspec tough is "W", as in 5Y3WGTA.

The "EB" suffix on Russian types is also an indication of suitability in military applications. Another Russian suffix indicative of a military rating is "ДР", which transliterates as "dr".

Perhaps Victor Khomenko will expound in detail about Russian suffixes.
