A 2009 review described Hezbollah in summary as "capable of tactical actions that are much more complex than a typical non-state belligerent. They show sophistication and the clear ability to conduct major combat operations." Analysts widely consider the group an "exceptionally capable organization" and one of the world's most innovative armed non-state actors. Hezbollah is considered to be more capable than Palestinian groups in terms of training, discipline, and central command. In the 2006 war, Hezbollah was able to execute mission-type orders, which improved its combat effectiveness, but was still severely outmatched by the IDF in one-on-one fighting. In the 2006 war, fighters had the autonomy to operate without direct orders in case they got cut off. However, it appears that this was not necessary, as a chain of command was maintained throughout the war. Although Hezbollah's mission command enabled local leaders to take the initiative and be flexible, it also meant that Hezbollah units were not able to support each other in battle. Hezbollah squads generally, but not always, comprised about seven to ten men. They had a great deal of autonomy and self-sufficiency, but also had a chain of command up to Beirut. Hezbollah's use of stockpiles, instead of a logistics train, and the "high degree of autonomy given to junior leaders" differentiate it from normal Arab armies. Hezbollah practices decentralized mission command where top leadership is responsible for long-term planning but not generally for tactics or operations. In 2006, Hezbollah's style of mission command and high autonomy resulted in the organization behaving on the battlefield similarly to the IDF. Hezbollah's command and control is effective but "low-tech". It is composed of wire, fiber optic, runners, signals, and the civilian communication network. Hezbollah rarely emits radio-electronic spectrum. Hezbollah is very pliant to Iranian interests, but does not seem to be controlled directly by Iran. Hezbollah's status as a Lebanese nationalist movement, and its need to maintain cross-confessional support, is possibly its biggest constraint to growth. Hezbollah is expanding from a powerful, localized asymmetrical actor into a regional military power.
