Taken from an educational book with parallel English literal translation. The original work is Mishima's "Patriotism".
麗子は良人の親友であり、たびたびこの家へも遊びに来た元気な青年将校の顔を思い浮べた。
Reiko recalled the faces of the cheerful young officers who were such dear friends of her husband and had often paid social visits to the house.
What I'm having trouble with is the copula:
麗子は良人の親友であり、たびたびこの家へも遊びに来た元気な青年将校の顔を思い浮べた。
With that translation, I'd expect the sentence to look like:
麗子は良人の親友、たびたびこの家へも遊びに来た元気な青年将校の顔を思い浮べた。
Where relationship between 親友 and 顔 is copulative and the sentence becomes
麗子はXを思い浮べた。 Reiko recalled X (the noun phrase that describes the officers).
In other words, I am very confused about the original sentence's grammar and looking for an explanation how it turns into what it was translated into in the educational text.
