This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.163.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 17:28, 10 March 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

[[File:Salvage diver.jpg|thumb|right|A U.S. Army Diver surveys the "sail" of a Soviet era submarine during a joint Army/Navy submarine salvage operation in the Providence River, Providence, RI, July 26, 2008.]]
'''Army engineer divers''' are members of national armies who are trained to undertake tasks underwater, including [[reconnaissance]], [[demolition]], and [[Salvage diving|salvage]]. These divers have similar skills and qualifications as [[professional diver]]s. Army divers use both surface supplied "Hard hat" and [[Scuba diving|SCUBA]] to perform their missions. In the [[United States Army]], they are members of the [[United States Army Corps of Engineers|Corps of Engineers]]. In the [[British Army]], they may be '''Royal Engineer Divers''' or '''Commando Engineer Divers'''.

==Description==
[[File:For Army divers, excavating underwater tombs is a solemn, honorable duty fDNqXzxVBAE.webm|thumb|Army's 7th Engineer Dive Detachment]]
Army engineer divers are members of national [[armies]]. Army engineer divers are trained in underwater [[construction]], [[Salvage diving|salvage]], [[demolition]]s, [[hydrographic survey]], hyperbaric chamber operation, beach and river [[Reconnaissance|recon]], bridge recon, [[underwater cutting and welding]], [[Side-scan sonar|side scan sonar]] operations, [[Naval mine|mine]] and [[countermine]] operations, and search and recovery operations. They are also training in [[ships husbandry]] operations. These divers have similar skills and qualifications as [[professional diver]]s. 

== Notable operations ==

=== Port-au-Prince, Haiti, 2010 ===
[[File:US Navy 100208-N-1134L-143 Divers wraps wire around adjoining pieces of re-enforcement bar used to strengthen sections of pier in Port-au-Prince, Haiti.jpg|thumb|Army Divers work to repair a portion of the main port in [[Haiti]].]]

The [[2010 Haiti earthquake|earthquake of January 12, 2010]], that left thousands of [[Haitians]] dead or homeless and hungry, rocked Haiti's main port of [[Port-au-Prince]]. Shockwaves sent the port's busy northern pier and its two massive cargo cranes sinking into the sea. The harbor was littered with toppled shipping containers. The southern pier was sheared from its concrete support pilings. The U.S. military worked with Haitian authorities to offload seaborne humanitarian aid and commercial cargo as it helped run the port. At the heart of its plans was an effort to repair the remains of the southern pier, leaving Haiti with a vital avenue for humanitarian aid and commerce.

==Equipment==
((prose|section|date=October 2012))
* Hard hat [[Diving helmet]] that is utilized for surface supplied diving
* Standard [[full face diving mask]]
* [[SCUBA diving]] equipment that is regularly utilized for high mobility missions

==Physical fitness test==
Diving medical personnel evaluate the fitness of divers before operations begin and are prepared to handle any emergencies which might arise. They also observe the condition of other support personnel and are alert for signs of fatigue, overexposure, and heat exhaustion.

== Affiliations ==
In the [[United States Army]], engineer divers are members of the [[United States Army Corps of Engineers|Corps of Engineers]]. In the [[British Army]], they may be Royal Engineer Divers or Commando Engineer Divers.

=== Royal Engineers and Commandos ===
[[File:The British Army on the Western Front, 1914-1918 Q8898.jpg|thumb|Diver of the Royal Engineers descending to repair the foundation of a bridge on the canal at Watten, 8 June 1918.]]

In the [[British Army]], the [[Corps of Royal Engineers]] has a specialist role of Royal Engineer Diver dating back to 1838 under Colonel [[Charles William Pasley]]. They are trained at [[Horsea Island]] alongside [[Royal Navy]] divers for the tasks required of an engineer diver, such as underwater thermic lance cutting, concreting and demolition.<ref name="royal engineers">((cite web |title=The British Army - Royal Engineers Diver |url=http://www.army.mod.uk/royalengineers/26639.aspx |access-date=17 April 2017 |website=UK Ministry of Defence |archive-date=18 April 2017 |archive-url=https://web.archive.org/web/20170418084450/http://www.army.mod.uk/royalengineers/26639.aspx |url-status=live ))</ref> In addition, the reserve [[Commando]] Engineer Divers of [[131 Commando Squadron Royal Engineers]], a part of the [[24 Commando Regiment (United Kingdom)|24 Commando Engineer Regiment]] Dive Team, are trained as divers to the same standards.<ref name="commando">((cite web |title=The British Army - Commando Engineer Diver |url=http://www.army.mod.uk/royalengineers/units/40591.aspx |access-date=17 April 2017 |website=UK Ministry of Defence |archive-date=18 April 2017 |archive-url=https://web.archive.org/web/20170418084448/http://www.army.mod.uk/royalengineers/units/40591.aspx |url-status=live ))</ref>

=== US Army ===
Deep sea divers have been a part of the United States Army since the [[Spanish–American War]]. In 1898, they constructed a [[cofferdam]] around the ((USS|Maine|ACR-1)) to facilitate the ship's inspection and determine the cause of its sinking. Later, during World War I, Army divers built and inspected bridges, tunnels, and port facilities.

As part of the U.S. Army Port Construction and Repair Groups, U.S. Army divers operated throughout the [[European Theatre of World War II|European]] and [[Asiatic-Pacific Theater|Pacific theaters]] during World War II. Divers performed salvage, demolition, pier construction, and bridging support.  As part of the [[Normandy landings]], U.S. Army divers participated in operations at [[Utah Beach]]. They were also employed in rebuilding the port of [[Cherbourg]] following its capture. Later they were employed to reopen the [[Albert Canal]] from [[Liège]] to [[Antwerp]], and assisted in the construction of the first Allied railroad bridge across the [[Rhine River]], while in the [[Philippines campaign (1944–1945)|Philippines]], they undertook salvage operations in various ports and rivers.

During the [[Korean War]], Army engineer divers worked with Port Construction Companies to build and maintain pipelines in the ports of [[Inchon]] and [[Pohang]], and reconstruct the locks in the port of Inchon. Later, during the [[Vietnam War]], Army divers constructed ship-to-shore petroleum distribution and port facilities in [[Cam Rahn Bay]] and [[Qui Nhon]]; they also constructed ammunition piers, and conducted body, helicopter and vehicle recoveries throughout the theater.

In 1989 during [[Operation Just Cause]], U.S. Army divers from the [[536th Engineer Battalion]] 7th Dive Detachment performed base security at [[Howard Air Force Base]] and conducted body recover of ((abbr|MIA|missing in action)) pilots and aircraft [[OH-58]] salvage operations in the [[Panama Canal]].

In 1991 during [[Operation Desert Storm]], divers deployed to Kuwait to engage in recovery operations after the ground war, clearing the Kuwaiti port of [[Shuaibah]] by removing debris and damaged Kuwaiti and Iraqi boats from the port.

Since then, U.S. Army divers have also supported port opening and reconstruction efforts in military operations in Somalia and Haiti. After 2002, U.S. Army divers have been continuously deployed foreword to the [[CENTCOM]] area of operations, including [[War in Iraq|Iraq]], [[War in Afghanistan (2001–present)|Afghanistan]], Qatar, Oman, United Arab Emirates, Bahrain, and Jordan. In these areas, U.S. Army divers have provided commanders on the battlefield with maneuver support, conducting operations such as search and recovery, river reconnaissance, construction and repair, demolition, salvage, port clearance and security, ships husbandry, and [[hydrographic survey]]s.

Army engineer divers continue to represent the vast capabilities of the U.S. Army Engineer Regiment by providing expeditionary engineer diving capabilities in support of combat, general, and geo-spatial engineer across the full spectrum of U.S. military operations worldwide. Throughout the history of their employment in the U.S. Army, divers have been organized under various commands and units, ranging from Engineer Port Construction to Transportation Support Commands. Currently, they are organized into five detachments (74th Engineer Dive Detachment, 86th Engineer Dive Detachment, 511th Engineer Dive Detachment, 569th Engineer Dive Detachment) at [[Joint Base Langley–Eustis]], Virginia, and one detachment (7th Engineer Dive Detachment) at [[Joint Base Pearl Harbor–Hickam]], Hawaii. Throughout the various conflicts in which Army divers have been employed, they have trained and fought alongside counterparts from the [[US Navy]]. Therefore, the co-location at the Naval Diving and Salvage Training Center is a fitting representation of their intertwined and storied history.
