Chapter V V-16 JP 3-0 conducted under FHA operations, humanitarian and civic assistance programs generally encompass planned activities in the following categories: (a) Medical, dental, and veterinary care provided in rural or underserved areas of a country. (b) Construction and repair of basic surface transportation systems. (c) Well drilling and construction of basic sanitation facilities. (d) Rudimentary construction and repair of public facilities such as schools, health and welfare clinics, and other nongovernmental buildings. j. Protection of Shipping. When necessary, US forces provide protection of US flag vessels, US citizens (whether embarked in US or foreign vessels), and US property against unlawful violence in and over international waters (such as Operation EARNEST WILL, in which Kuwaiti ships were reflagged under the US flag in 1987). This protection may be extended to foreign flag vessels under international law and with the consent of the flag state. Actions to protect shipping include coastal sea control, harbor defense, port security, countermine operations, and environmental defense, in addition to operations on the high seas. Protection of shipping, which is a critical element in the fight against piracy, requires the coordinated employment of surface, air, space, and subsurface units, sensors, and weapons, as well as a command structure both ashore and afloat and a logistic base. Protection of shipping may require a combination of operations to be successful. These actions can include area operations, escort duties, mine countermeasures, and environmental defense missions. k. Show of force operations are designed to demonstrate US resolve. They involve the appearance of a credible military force in an attempt to defuse a situation that, if allowed to continue, may be detrimental to US interests. These operations also underscore US commitment to our multinational partners. (1) The US deploys forces abroad to lend credibility to its promises and commitments, increase its regional influence, and demonstrate its resolve to use military force if necessary. In addition, SecDef orders a show of force to bolster and reassure friends and allies. Show of force operations are military in nature but often serve both diplomatic and military purposes. These operations may influence other governments or politico-military organizations to refrain from belligerent acts. SHOW OF FORCE IN THE PHILIPPINES Operation Joint Task Force-PHILIPPINES was conducted by US forces in 1989 in support of President Aquino during a coup attempt against the Philippine government. During this operation, a large special operations force was formed, fighter aircraft patrolled above rebel air bases, and two aircraft carriers were positioned off the coastline of the Philippines.
