The named women are Karin (Gerry's wife) and Segen, a soldier. The two other named female characters are Gerry's two young daughters Rachel and Constance. No named adult women talk to each other in the movie, but the daughters speak to each other very briefly in small, non-plot relevant scenes. Karin also plays a guessing game with her daughters and tells Rachel that Rachel's grandmother is British.
Some detailed asides which have to do with gender portrayals in the movie, but don't affect the Bechdel rating:
The negative aspects of nature are personified as Mother Nature, a serial killer "bitch."
Segen is a female soldier and is portrayed in a non-sexualized, competent, completely standard movie soldier way. Excepting maybe that kiss on the head.
Brad Pitt's character is a house-husband and it is not denigrated or played for laughs. His competence as a parent is shown as natural for someone with military competence, and vice versa.
Karin has to be rescued from an attempted rape.
Gerry's wife and children are used as his character motivation.
Gerry tells a young boy to protect "the ladies" (including Karin, an adult woman) and calls him "tough guy," in contrast to calling his own daughter a baby and (after she protested she wasn't a baby) a "beautiful" small adult.
