"Army Wives,” Lifetime's most successful series in the network's history, returns with its sixth season and a two-hour premiere event of back-to-back all-new episodes on Sunday, March 4 at 9 pm et/pt. The show follows the struggles, dreams and friendships of a diverse group of women — and one man — living with their spouses and families on an active Army post. Kelli Williams ("The Practice") joins the cast this season, playing Jacqueline "Jackie" Clarke, the ambitious wife of two-star Major General Kevin Clarke. Television icon Susan Lucci ("All My Children") makes several guest star appearances as Audrey, the wife of a retired Brigadier General, reuniting her with her former "All My Children" co-star Delaney.
