The frontal attack is usually the least desirable form of maneuver because it exposes the majority of the offensive force to the concentrated fires of the defenders. The battalion may conduct a frontal attack against a stationary or moving enemy force (Figure 4-6).
All of the twelve ribs articulate posteriorly with the vertebrae of the spine. Each rib forms two joints: Costotransverse joint â Between the tubercle of the rib, and the transverse costal facet of the corresponding vertebrae.
Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12).
