Forgotten units level on attack

I don't know if it's a mistake or if it's a correct operation but since it seemed strange to me I put it here for review.

Is it normal that a world where the maximum level is 65 (Tiberian 35 Europe) the forgotten ones attack you with level 66 units?

Thank you in advance.
