A great review of Will Eisner's Last Day in Vietnam from the PopMatters Comics Blog:
In the titular story from Will Eisner's anthology Last Day In Vietnam, an unnamed Major in the USMC and civilian news-reporter plan an impromptu escape from a Marine Firebase.
The beauty of this sequence lies in Eisner's superb skill at telling a story across dimensions.

Viewed from inside the Huey, the Major running towards the chopper is ordinary fare for comics. It is the world at a distance, the theatrical fourth wall remains undisturbed. But over the course of the two panels that follow, the fourth wall is breached and the violence and horror of a base camp under enemy fire recedes into the distance.
