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.
The body of the sternum articulates above with the manubrium by means of a fibrocartilaginous joint (a symphis) called the manubriosternal joint, which allows slight movement between these two parts of the sternum when the ribs rise and fall during breathing.
