Walking

Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk.

In the United Kingdom and Ireland, the term walking includes activities such as walking in a park and trekking in the Alps. However, in Canada and the United States the term for a long, vigorous walk is hiking, while the word walking covers shorter walks, especially in an urban setting.

Horse gait

Horse gaits are the various ways in which a horse can move, either naturally or as a result of specialized training by humans.

Classification

Gaits are typically categorized into two groups: the "natural" gaits that most horses will use without special training, and the "ambling" gaits that are various smooth-riding four-beat footfall patterns that may appear naturally in some individuals, but which usually occur only in certain breeds. Special training is often required before a horse will perform an ambling gait in respond to a rider's command.

Another system of classification that applies to quadrupeds uses three categories: walking and ambling gaits, running or trotting gaits, and leaping gaits.

The British Horse Society Dressage Rules require competitors to perform four variations of the walk, six forms of the trot, five leaping gaits (all forms of the canter), halt, and rein back, but not the gallop. The British Horse Society Equitation examinations also require proficiency in the gallop as distinct from the canter.

Mamasapano clash

The Mamasapano clash, also known as the Mamasapano Massacre, was a police operation, codenamed Oplan Exodus, which took place on Sunday, January 25, 2015, at Tukanalipao, Mamasapano, Maguindanao, by Special Action Force (SAF) of the Philippine National Police (PNP) (allegedly joined by United States Army Special Forces) against the Bangsamoro Islamic Freedom Fighters (BIFF) and the Moro Islamic Liberation Front (MILF). The operation was intended to capture or kill wanted Malaysian terrorist and bomb-maker Zulkifli Abdhir and other Malaysian terrorists and/or high-ranking members of the BIFF.

Originally a mission to serve arrest warrants for high-ranking terrorists, it led to the deaths of 44 members of SAF, 18 from MILF and 5 from the BIFF, and several civilians, and the death of Zulkifli Abdhir confirmed by the FBI and the PNP at 6:30 p.m. of February 4, 2015 due to a matching DNA result. He was one of FBI's most wanted terrorists. Getulio Napeñas, the relieved SAF commander, estimates about 250 deaths from the combined MILF, BIFF, and private militias during the encounter although this was not confirmed and was met with skepticism since aside from the fact that there was no actual body count, there is no acceptable level of evidence to prove his claim. Napenas' estimate was also debunked by the MILF and by the local government of Mamasapano.
