原文
The intern whom I mentioned last time with excellent communication skills had been in US army for three years.
He told me last Sunday after he solved another case perfectly. I wondered his experience before he was admitted in the residency program. And he told me the details. He said for the first sixth months in military traning， it was very tough. For a whole 連隊（英文怎麽說？I forgot now）， if only one person made a mistake，than the whole 連隊 would do the training again， including wearing suits， running， etc. Sometimes， over one night， they had this traning several times.
So， the training in US army is very tough. The intern got promotion in the army.
It is not surprising that he could solve some tough scenarios smoothly as an medical intern. He had excellent review in recent interns evaluation meeting by all of attendings who worked with him.
Exemplar of native or native like English:
It turns out that intern with excellent communication skills, whom I mentioned in a previous post of mine, had been in the US Army for three years. Last Sunday after he had solved another thorny case perfectly he told me this when I inquired about his pior experience before being admitted into the residency program. He let me in on some very interesting details. He said the first sixth months of military training were the toughest. Even if just one of them messed up，the whole company would have to repeat whatever training routine they were going through，be it suiting up，running，and what not. Sometimes，they had to pull an all-nighter until everyone passed muster.
So it seems that training in the US Army is very tough. The intern did very well and got promotion in the Army.
Given this background, it's no surprise that he can function competently in tough scenarios as a medical intern. At a recent intern evaluation meeting, he received excellent reviews from all the attendees who had worked with him.
