By Dialogo November 01, 2011 From October 24 to November 1, 2011, Brazilian Army’s 2nd Division carried out Operation Quebra-Canalha (Crook Breaker) II – an advanced training exercise aimed at preparing the division’s command beyond the 11th and 12th Infantry Brigades and other military units belonging to the country’s Army in foreign defense operations. The exercise took place in Vale do Paraíba, and included various municipalities within São Paulo state. The troops concentrated on October 24. The day after, on October 25, the 2nd Division Command issued its Operations Order unchaining the brigades’ plans. At night on October 26, the 11th Infantry Brigade lead a night infiltration and repositioning opportunity in Paraíba do Sul River, with the support of the Divisionary Engineering unit and ended the action by surrounding and assaulting the locality of Cachoeira Paulista. On October 26, the 12th Infantry Brigade infiltrated its reconnaissance platoons aimed at the mobile air assault that took place on October 28. The Brazilian Army’s Aviation Battalion (BAvEx) was in flight during 110 hours, fulfilling mobile air assault missions, mobile air supply, command and control, and transport, employing the 2 HA-1 (Esquilo), 4 HM-1 (Pantera) and 1 HM-3 (Cougar) helicopters. The reconnaissance and attack and general use helicopter fleet bases, as well as their organic means, were deployed on the terrain. All the BavEx Operation Base’s deployments took place through means transported by helicopters that were specifically designed for this end. The unit employed specialized personnel along with air space control units, which proved vital in allowing the quick coordination of actions and avoiding conflict between the military operation and normal aircraft traffic, thus keeping air support constant, operational and safe.
