They're ex-East-German, modified in West Germany to SPz BMP-1A1 standard. Afaik all BMP1 exported to Greece were BMP-1A1.
Nothing special.
BMP-1A1 means they have the AT-3 launcher removed (and AT-5 added), 73mm autoloader removed, fuel cells in back doors removed. Western standard smoke grenade launchers added. Fifth gear was blocked, lowering speed to 40 kph max; modified transmission for better handling. Boarding ladder on the left side of the vehicle, some anti-sliding covering of the hull. Added crew compartment heating. Rubber track pieces originally planned for German service, as the BMP-1A1 didn't get a road license due to its metal tracks.
Later Greek upgrades included a M2HB for the TC.
