(CNN) —  

I don’t know Lt. Col. Alexander Vindman personally. But his story, background, service record, skills and attributes are like those of so many others I have served with during assignments in Europe and the Middle East.

Vindman, the National Security Council’s top Ukraine expert, is in the news as he is testifying before a House impeachment inquiry about his concerns over President Trump’s request that Ukraine’s president investigate Trump’s political rival. Because he questioned this — indeed he reported it to NSC counsel – Vindman has taken a great deal of criticism from President Trump’s defenders in recent days.

If you have been following along with the impeachment inquiry, you likely know at least some of Vindman’s own story. He came to this country with his parents from another country — Ukraine – that was within the boundaries of the then-Soviet Union. When he arrived as a three-year-old, the army in Europe was patrolling the borders of the Warsaw Pact and preparing for the invasion of the Soviet forces. Crazy times.

Vindman grew up in a family that knew the oppression of authoritarianism, and by his testimony we know his family instilled a passion for patriotism and service to his new country. He went to school, enrolled in ROTC, and upon commissioning, chose to be an infantry officer. By then, the Iron Curtain in Europe had come down and his country of birth – Ukraine – was emerging as a sovereign state.

Before he was promoted to major, Vindman like all Army officers was asked to choose a “functional area.” There are many of these offered – public affairs, strategist, operational research, etc. – and all majors understand that service and assignment in their chosen area will complement the requirements of their basic branch (in Vindman’s case, infantry). Though he had served as an infantryman, Vindman’s background, language skills, and cultural understanding likely contributed to him choosing Foreign Area Officer, or FAO.

Being an FAO is tough. Qualifications requires attendance at a graduate school to learn a nation or area’s culture, expertise in a language, extensive training in ethics, tougher vetting than what is given for other officers when applying for a security clearance, and service in a key position, like a critical staff or an embassy. FAO’s spouses are also vetted, given that they are usually asked to accompany the officer to foreign lands and interact with locals.

In fact, the preparation and qualification processes are so rigorous that many who become FAOs eventually “single track” in that area – meaning they usually don’t have the time to return to their basic branches.
