Why do they need 'tanks'? Mobile infantry not enough? I for the life of me can't figure out why Israel would allow Egyptian tanks into the Sinai. I would imagine ( hope ) that the number of tanks is limited to only a few. Again why is it the Egyptians are using 'tanks'. Only thing I could think of was a place the Egyptian infantry units could hide behind. lol Seriously though, any tankers out there know why they need tanks to patrol for infiltrators? I would think that mobile and tracked' personnel carriers would be what's needed.
