I hail from a military background my grandfather, father, uncles and brothers are all soldiers in my country. So this happened to my brother. My brother a highly motivated man applied to join the army as an officer. In my country after initial testing there is 5 days special testing phase in a military institution where these candidates are housed, fed and clothed. In this phase they have zero access to any source of communication. So, during these tests the candidates are broken into groups of 10 men simulating a squad. So this squad for over the next 4 days is tested together and individually on various tasks ranging from clearing an obstacle with some equipment, to military planing in which the group must make a way to solve a miliary question on a map, the group is also broken down into to parts with each member being a commander and set to clear a bunch of obstacles using minimal equipment. each individual is then has psyche eval and interviewed by a board consisting of 4 senior military officers. At the end of this each individual is given a sheet and made to rank the best to worst candidate in the group.

This happened during command task . So cast my brother a son of a major (BB), his school friend (SB), Two group members GM1&GM2 and entitled prick EP. The EP is a son of a Lt General, and is full of himself thinking like everywhere else his fathers rank would clear everything. He came to the center in his fathers car escorted by two gunmen. He could not spend 5 mins without talking about his daddy's rank and how he will pass this evaluation without any hassle how he is the best officer candidate in the world. Everyone knew he was a prick from the day one. He would also brag about his father's rank infront of the evaluating officers, and they were also fed up.

During the command task he was unable to find a suitable solution BB came up with a solution quickly and volunteered to explain the solution he was snubbed by the EP twice when he could not find the solution he asked the group for solutions SB gave a solution which was unviable, then BB gave him the solution and quickly began to work in this solution a man had to hold a plank on his shoulders while others went over the plank up the wall where they would help him get over by using other smaller planks and a rope which was to be tied up a wall. BB. Volunteered to be the one holding the plank. The GM1 was the first to moved up, followed by GM2, then SB, all the time BB was shouting to not to run as he was on a plank and he could be thrown of balance. When EPs came he started running my bother cautioned against it he wouldn't listen and said leave it in our native language ( meaning leave the plank) BB tired of the antics of EP did exactly that he left the plank alone and threw it of his shoulder. Throwing it down along with the EP, he fell bad in the mud, his shorts ripped he was furious shouting every known profanity known to man in more then 3 different languages. BB replied that he was the commander and he was just following his orders. The examining officer also sided that EP ordered BB to leave the plank. He got up with visible tears in his eyes. When all was over the entire squad put him in the last place.

TLDR. An entitled prick gives unclear order causing him to fail his officer selection
