There are two significant things to take from the news that Army Wives will return for a fourth season. One, the predominantly female viewership of Lifetime has embraced the series about the lives of Army personnel and their families on the Fort Marshall post in Charleston, South Carolina; and two, scripted dramas are on the rise all across the cable networks. It also means that this finely acted, well-written and well produced show is going to be around for the next couple of years at least.
