The greek army has purchased some M113A2s (doesn't say number), M901A1/A2 (50-80), and AAV-7 (100 vehicles) armed with 12.7mm hmg and 40mm MK-19.
In the same article it says there are plans for the 30 BMP-3Fs, to not be acquired and instead be replaced with something else. (the 420 BMP-3Ms order still standing)
