Sas Troop,
In the "Search" use
"TWARDY" it'll show the most search results at 14 dating back to 8/05. As to ERAWA it's not true ERA, but, more like a Ceramic Tile add on armor with characteristics
similar to NERA (But not as good.). The
key difference is in the spacing/gap of the tiles vs standard ERA which does provide some added protection especially against tandem rounds.
Don had addressed the armor issue for the 5.5 release.

ERAWA-2...
Was an improvement to ERAWA-1 as tested in ref. 2 above. It is a dual layer material, however, it is still susceptible to KE rounds, which Poland hopes to solve with ERAWA-3. Due to the time, I have no information concerning it's development or current status.
The PT-91M was delivered with ERAWA-2 to Malaysia.
