This field defense, especially the machine gun position setup and the firepower arrangement for VIP protection, is indeed quite different.
According to Patrick's plan, he set his machine gun positions at the highest points across the island, with at least one machine gun each, the large-caliber type, with a range that basically covers the entire island.
But now the focus of defense is the small residential buildings used for daily living, so setting machine gun positions at the highest peak of the small island seems a bit too far away.
Moreover, considering that enemies who engage with Mad Dog are always equipped with heavy body armor, it doesn't matter if they have this habit or not, as long as they know they're up against Mad Dog, they will definitely choose heavy body armor and heavy-duty ballistic masks. In view of this common trait of the enemy, the firepower of Patrick's main MG5 machine gun seems a bit insufficient.
