So, how does the enemy respond differently, when confronted with squads of PDW's?

Presumably, he makes taking out the crew-served and special weapons a fetish - it becomes his #1 tactical priority, and once that is accomplished, manuevers agressively to suppress and destroy the squad...?

I am not necessarily disagreeing with the idea of a platoon/squad partially equipped with PDW's, just wondering out loud if it makes the enemy's job a little easier, or allows them to focus better (since they should be focused on taking out the special weapons anyway).
