I just started playing the scenario Mejel Mayhem and the PzII’s are Panzer II L "Lynx" not the J’s.
These J models had the equivalent armor of the Russian KV1 and certainly would not be knocked out by an Allied light tank from the front.
In CM1 they were used on the Russian front only.
According to Wikipedia:
Panzer II Ausf. J (Pz.Kpfw. IIJ)
Continued development of the reconnaissance tank concept led to the much up-armoured Ausf. J, which used the same concept as the Pz.Kpfw. IF of the same period, under the experimental designation VK 1601. Heavier armour was added, bringing protection up to 80 mm on the front (similar to the maximum armour found on the KV-1 model 1941 Soviet heavy tank and 50 mm to the sides and rear, with 25 mm roof and floor plates, increasing total weight to 18 tonnes. Equipped with the same Maybach HL45 P as the Pz.Kpfw. IF, top speed was reduced to 31 km/h (19 mph). Primary armament was the 2 cm KwK 38 L/55 gun. 22 were produced by MAN between April and December 1942, and seven were issued to the 12th Panzer Division on the Eastern Front.
This is a Panzer II Ausf. L in the Musée des Blindés, Saumur.

This vehicle that was named after a mythical creature will forever be associated with the famous legendary Desert Fox..."

"...the griffin, griffon, or gryphon is a legendary creature with the body, tail, and back legs of a lion; the head and wings of an eagle; and sometimes an eagle's talons as its front feet. Because the lion was traditionally considered the king of the beasts, and the eagle the king of the birds, by the Middle Ages, the griffin was thought to be an especially powerful and majestic creature. In medieval heraldry, the griffin became a Christian symbol of divine power and a guardian of the divine..."
