Jun had never expected that the situation would be overturned the moment they came in.
First of all, Clovis surprised him by the fact that he knew about the ambush. No, he was faking it so that they would fall into his trap.
Then, Clovis set up his own person to ambush their snipers. It could be said that he had underestimated Clovis' people.
