Throughout the film, Chris’ ability and attempts to understand the big picture of war illustrate how he views situations from a holistic, female mental sex standpoint.  As an example, he is able to home in on who it is that is called to war, and who is excused:
KING:  How the fuck you get over here man, you look like you educated…
CHRIS:  I volunteered.
KING:  You what?  Say ‘gain.
CHRIS:  Yeah, I dropped out of college and told ‘em I wanted infantry, combat, and Nam…
He grins, finding their reactions funny.  It’s also the first time we’ve seen Chris crack a smile.
CRAWFORD:  You volunteered for this shit, man?
KING:  You a crazy fucker, givin’ up college, man.
CHRIS:  Didn’t make much sense.  Wasn’t learning anything…  (hesitate) And why should just the poor kids go to the war - and the college kids get away with it.
King and Crawford share a smile.
KING:  What we got here a crusader?
CRAWFORD:  Sounds like it. (Stone, P. 24)
Even though he didn’t see Barnes actually shoot Elias, or has any physical proof of the crime, Chris still knows Barnes murdered Elias.  Chris’ beliefs are derived from the tense, volatile relationship between Elias and Barnes, and the horrible scene where Elias runs from the jungle only to get killed by the enemy soldiers pursuing him.  This sight directly contradicts Sgt. Barnes questionable account of how he earlier found Elias dead in the jungle, prompting the following exchange of dialogue between Chris and other platoon members:
CHRIS:  He killed him.  I know he did.  I saw his eyes when he came back in…
RHAH:  (puffing on his bowl) How do you know the dinks didn’t get him.  You got no proof man.
CHRIS:  Proof’s in his eyes.  When you know you know.  You were there Rhah - I know what you were thinking.  I say we frag the fucker.  Tonight. (Stone, p. 85)
Another instance that illustrates how Chris looks at the war from an overall, holistic standpoint is in the last conversation he has with King:
CHRIS:  Y’ever get caught in a mistake, King, and you just can’t get out of it?
KING:  Way out of anything, man.  Just keep your pecker up and your powder dry, things change.  How many days you short?
CHRIS:  Not just me… it’s the way the whole thing works.  People like Elias get wasted and people like Barnes just go on making up rules any way they want and what do we do, we just sit around in the middle and suck on it!  We just don’t add up to a rat’s ass.
KING:  Whoever said we did, babe.  Make it outta here, it’s all gravy, every day of the rest of your life - gravy…(Stone, p. 95)

The female mental sex character resolves problems by comparing surpluses to deficiencies, and then taking steps to create a balance. When Guy first refuses to go to the Castevets for dinner, even though Rosemary makes it clear that she promised Mrs. Castevet, she begins reasoning out loud why they should stay home—creating a surplus of reasons acquiesce to Guy’s wishes. She doesn’t push Guy, but eventually he says, “Let’s go.” When her pregnancy becomes a seeming never-ending agony, and no one will listen to her, she throws a party where her friends can assess her shocking physical and emotional condition and push her to see a new doctor. When she grows weary of Minnie’s meddling, she accepts Minnie’s “herbal” drink, but then pours it down the drain. Thus she is dealing with the immediate surplus, but not yet taking steps to resolve the whole problem. When she discovers the truth about her baby, she is armed with a butcher knife as if she is willing to strike at one of the perpetrators, or even her baby. But she is confronted with a different inequity: the need of her baby. The story ends with Rosemary “becoming” the mother to her child, having seen the real deficiency in the situation, the baby’s lack of a mother.
