Editing Backpack (section)

==Professional use==
Backpacks are a standard part of the load-bearing equipment of soldiers, especially [[infantry]],<ref>{{cite book|first=W.Y.|last=Carman|page=99|title=A Dictionary of Military Uniform|date=1977 |publisher=Scribner |isbn=0-684-15130-8}}</ref> in most countries, and military-style packs are regularly available to civilians in [[military surplus]] stores. Well-known examples include the United States [[All-purpose lightweight individual carrying equipment|ALICE field pack]] and the British Army [[personal load carrying equipment|PLCE]] rucksack attachment, both of which are widely available to civilian markets both as actual military surplus (new or used) and as replicas. Such packs are often, though not always (e.g. the [[United States Marine Corps|USMC]]'s [[Improved load-bearing equipment|ILBE]] pack), external-frame packs, with the pack itself lashed or [[Circle cotter|pinned]] to a metal or plastic carrying frame. For units that are entering combat situations, packs may be loaded heavily and can weigh in excess of {{cvt|100|lbs|kg|0}}. Each soldier may carry extra weapons, ammunition, rations, medical supplies, tents or other shelter material, and extra clothing.

Many police tactical units, as well as players of military-style combat games such as paintball and airsoft, use these military-style tactical backpacks and webbing for storing gear and ammunition. There is also a small but thriving industry devoted to creating historical reproductions of military gear; such companies generally produce period-appropriate uniforms and other gear in addition to backpacks.

Some more recent military/tactical designs, especially the [[MOLLE]] and [[ILBE]] packs used by the United States armed forces, are covered with webbing loop attachment points for increased carrying capacity.

Recently, at least one brand of backpack has been specially designed for professional cooks and culinary students. This sort of backpack is meant to safely carry knives, cooking tools, and other miscellaneous equipment such as notebooks, towels, and uniforms.

Specialist backpacks are used by fire services for wildfire fighting, as well as by rescue services for Search and Rescue. These backpacks are generally very modular, allowing the pack to be reconfigured to the users wishes and are designed to load around the wearers hips. They may include features such as sections for water bladders and specially designed pouches, such as those used to carry personal fire shelters.
