What is the M3/75 in La Campagne de Tunisie?

[Blackcloud6]

The Special Rules in La Campaigne de Tunisie that matter to this discussion are:

8. Tank Destroyers.
The Italian Sem 47/32 and the American M6 are the only tank destroyers appearing in La Campaigne de Tunisie.

9. Open-Top AFVs (1.2).
The German SK233, SK10/4, and SPW-251, the Italian Sem 47/32, and the American M3 and M3A1 SC are the only open-top AFVs appearing in La Campaigne de Tunisie.

Coupled with the AFV and Tank definitions from the Series Rules I posted in the OP, I can only assume that designer intended that the M3/75 be treated as a tank in La Campaigne de Tunisie.  Thus, the M3/75 will have a Tank leader and Armor efficiency as stated in La Campaigne de Tunisie Special Rule 10 unless Leonard comes on here and says otherwise.
