This book was very insightful for me, the mother of four children raised in a Navy family, albeit in the 1980s and 1990s. Truscott's research is based on an earlier generation of military children, when mothers tended to be less independent and thus the family was more influenced by the father's departures.
The US military has changed in the years since this book was written and more attempts have been made to protect family life. Still, I took away an important point from this book which has been very helpful for us.
Children get into a rhythm of life--moving every four years while growing up did affect my children. They tend to do something "big" or disruptive every four years even as they grow to adulthood--whether it be move, get a new car, find a new job, get married, have a child of their own.
They, and we retired military parents, are used to having everything turn upside on a regular basis.
We really get a little bored if we don't do something!
