Article 100 of the LOFA also states that these positions, and several others such as Chief of Police and Head of the Presidential, may be held "only once during the military career and for a time no greater than two years". This results in a fairly high turnover in the Bolivian High Command with continued service being prohibited by law. The last changes in High Command, under the previous President Evo Morales, occurred on 24 Dec 2018, 11 Dec 2017, 29 Dec 2016, 30 Dec 2015, 18 Dec 2014, 13 Dec 2013 and 3 Dec 2012.
