What’s the problem with the defect father of Dongdaejanghang in the reserve army who suddenly spoke informally

(1)I got a call from the reserve forces training, and I got a report that Captain Dong spoke informally while calling his name
(2)When I asked for an apology, he said he came out as a red-handed man, asking what’s wrong with his father
(3)When the coverage began, he apologized belatedly and promised to prevent a recurrence
(4)The report was reported by reporter Y Kim Geunwoo
(5)Mr. A, who finished his military service four years ago
(6)I couldn’t hide my embarrassment when I got a call from Dongdae of the Reserve Army in Pohang, Gyeongsangbuk-do, saying I would guide them through the recent training
(7)It’s because Captain Dong, who had never seen his face before, suddenly called his name and spoke informally
(8)Mr. A called my real name ○○. So I asked him if he knew me, and he said he was the reserve army’s Dongjang
(9)I protested politely, but the reply was even more absurd
(10)Mr. A asked if you wanted to be called honorifics by your father, and he said things that made people a little bit ridiculous
(11)When the angry man A demanded an apology, the leader came out as a red-handed man
(12)Mr. B, the Marine Corps Reserve Captain ○○ Oh, my son has two children older than you now What does that matter Why should I know that Then you want me to talk up to you
