Seven Wonders The Tomb of Shadows

What I think about the Seven Wonders The Tomb of Shadows by Peter Lerangis  is. Why would the kids get machetes? They Recieved light body armor and a belt to hold knifes. I don't  think the machete is really nessessary for the kids. It might be hard to swing the blade and by the time they swing it at an enemy they might die. I think the knifes should helpful. It's not heavy so anyone can use it. Also the people who are attacking the island have guns. Instead of machetes they should have a vest and helmet for more protection against bullets. I also think a character might die in this attack. There might be hundreds of soliders on the island and if they get caught the soliders will alert the other soliders to kill them all. But they escaped into the forest so it might be hard for the whole group to die.
