A dismounted reconnaissance troop (DRT) is a reconnaissance unit found within U.S. Army RSTA squadrons that are part of infantry brigade combat teams (IBCTs). While a RSTA squadron serves as the primary reconnaissance element for its parent brigade, the DRT serves as the specialized reconnaissance element for the squadron when conducting clandestine reconnaissance and surveillance.

The doubled-rope technique (DRT or DdRT) is used to self belay the climber in such a way that the rope can be retrieved without going back up the tree. One end of the rope is fastened to the climber's saddle (harness), from there the rope passes around the tree and back to a friction hitch, which is also attached to the climber. This system ...
Simul-climbing (or using a running-belay) is a climbing technique where a pair of climbers who are attached by a rope simultaneously ascend a multi-pitch climbing route. [1] It contrasts with lead climbing where the leader ascends a given pitch on the route while the second climber remains in a fixed position to belay the leader in case they fall. [1]
In the 1930s, as caving became increasingly popular in France, several clubs in the Alps made vertical cave exploration an outdoor sport. During World War II, a team composed of Pierre Chevalier, Fernand Petzl, Charles Petit-Didier and others explored the Dent de Crolles cave system near Grenoble, France, which became the deepest explored cave in the world (-658m) at that time.
Climber leading a traditional climbing route, attempting to insert a nut for climbing protection.. Traditional climbing (or "Trad" climbing), is a form of free climbing (i.e. no artificial or mechanical device can be used to aid progression, unlike with aid climbing), which is performed in pairs where the lead climber places climbing protection into the climbing route while ascending.
The official climbing guidebooks were the first systematic forms of beta. [10] The beta in these physical climbing guidebooks was limited to the basic details of the climbing route (e.g. length, grade, direction/topo etc.) so as to manage the size of the guidebook and avoid giving so much information that would spoil an onsight attempt.

Therefore, the breastcollar is sometimes preferred on cross-country. The hunting breastplate also tends to have a restrictive effect on the shoulder, even when correctly fitted. Additionally, a hunting breastplate may cause the tree points of a poorly fitting saddle to dig into the sides of the horse's withers, creating rubs and great discomfort.
