=== Hand-trebuchet ===
The hand-trebuchet ({{langx|el|χειρομάγγανον, cheiromanganon}}) was a [[staff sling]] mounted on a pole using a [[lever]] mechanism to propel projectiles. Basically a one-man traction trebuchet, it was used by troops of emperor [[Nikephoros II Phokas]] around 965 to disrupt enemy formations in the open field. It was also mentioned in the [[Tactica of Nikephoros Ouranos|Taktika]] of general [[Nikephoros Ouranos]] (c. 1000), and listed in ''De obsidione toleranda'' (author anonymous) as a form of artillery.<ref>{{harvnb|Chevedden|2000|p=110}}</ref>

In China, the hand-trebuchet (''shoupao'') was invented by Liu Yongxi and presented to the emperor in 1002. It was a pole with a pin at its upper end that acted as a fulcrum for the arm. The pole was used as a shot for fixing in the ground and the user could then throw missiles at the enemy from a static position.{{sfn|Needham|1994|p=214}}

===Hybrid trebuchet===
According to Paul E. Chevedden, a hybrid trebuchet existed that used both counterweight and human propulsion. However no illustrations or descriptions of the device exist from the time when they were supposed to have been used. The entire argument for the existence of hybrid trebuchets rests on accounts of increasingly more effective siege weapons. Peter Purton suggests that this was simply because the machines became larger. The earliest depiction of a hybrid trebuchet is dated to 1462, when trebuchets had already become obsolete due to cannons.{{sfn|Purton|2009|p=382}}

===Couillard===
The '''couillard''' is a smaller version of a counterweight trebuchet with a single frame instead of the usual double "A" frames. The counterweight is split into two halves to avoid hitting the center frame.<ref>{{Cite web|url = http://www.thehurricanesracing.com/trebuchet.docx.html|title = Trebuchet Design Factors|date = 19 May 2015|last = Max|url-status = dead|archive-url = https://web.archive.org/web/20150604144937/http://www.thehurricanesracing.com/trebuchet.docx.html|archive-date = 4 June 2015}}</ref><ref>[https://www.chateau-baux-provence.com/en/siege-engines/couillard] {{Webarchive|url=https://web.archive.org/web/20220520202959/https://www.chateau-baux-provence.com/en/siege-engines/couillard|date=2022-05-20}} Couillard pictures ... see CHÂTEAU DES BAUX-DE-PROVENCE, France</ref>
