When Yodha repeated Sam's words and wanted to discuss things with them on how to improve quickly, he was met with resistance and reluctance from the special divisions as they were not ready to accept such insulting comments from someone who they never saw or heard of.
When the lightning division people asked Arman about him, all he replied are a few words.
"He is my Boss."
From this, they knew that he might be someone competent because even though these twenty-five people didn't fight against Arman, he has defeated quite a few people in the camp and almost destroyed every other elite other than these twenty-five people.
Sam knew something like this would happen. These soldiers are fed with some bullshit all saying that they are so elite and strong and they did prove to be the elites in some battles, but thinking that they are the only elites there is, that is utter bullshit.
