the height of natasha is not 6 Feet 8 Inches(in http://commandoshq.net/natasha_profile.htm)
i think it's 5 foot 8 inches - 6 foot 1 inches.
in fact green beret(6 Feet 5 Inches) is taller than natasha in commandos 2: men of courage

the thief is more like younger than other commandos, maybe he is younger more than ten or fifteen years than other commandos age

the spy is more older than other commandos in commandos 2: men of courage, his age(http://commandoshq.net/spy_profile.htm) more younger than driver, green beret, and sniper

that's all....
