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.
Scapulothoracic Joint. The scapulothoracic joint is not a true synovial joint. Rather, the scapulothoracic articulation is formed by the convex surface of the posterior thoracic cage and the concave surface of the anterior scapula.The scapula is a flat bone, with the gliding surfaces formed by the subscapularis and the serratus anterior.It is attached to the axial skeleton through the acromioclavicular joint and the sternoclavicular joint. The scapulothoracic articulation allows increased shoulder elevation.he scapula is a flat bone, with the gliding surfaces formed by the subscapularis and the serratus anterior.
