Should I change the Grenadiers into Pionieres?
Thanks for any opinions.

Regardless of the theatre of war, I always have both Grenadiers and Pionieres, a few Pionieres for mines or when a city needs to be taken quickly, and Grenadiers as they're generally the best infantry. Of course, a move hero is always handy to help with the lower move. Not really an answer to your question, but I've played Afrika Korps twice and don't remember doing any different as I always have more Pionieres anyway. It's been a while, but maybe AK has more minefields?

AK has more mines
