Command of the Brazilian army
Arruda was put in charge of the Brazilian army under Jair Bolsonaro on 30 December 2022, replacing Marco Antônio Freire Gomes. Júlio Cesar de Arruda was appointed in coordination with the transition team of Luiz Inácio Lula da Silva, so that the change of command would take place before Lula's inauguration. He was confirmed to his position by Lula's minister of defense José Múcio Monteiro on 6 January 2023.

2023 Brasília attack
On 8 January, pro-Bolsonaro rioters attacked federal buildings at the Praça dos Três Poderes in Brasília, many calling on the military to overturn the election results in which Jair Bolsonaro lost to Luiz Inácio Lula da Silva. In the aftermath of the attack, Lula administration officials arrived at the headquarters of the Brazilian Army to detain insurrectionists at a pro-Bolsonaro camp on the lawn adjacent to the army headquarters. The officials were faced tanks and lines of soldiers, and Júlio Cesar de Arruda told Minister of Justice Flávio Dino: "You are not going to arrest people here." Lula administration officials say this gave hundreds of insurrectionists an opportunity to escape and evade arrest.

President Lula blamed the intelligence services of the armed forces and the Brazilian Intelligence Agency for failing to alert him to the possibility of a coup attack. On 18 January, Lula affirmed that "Todos que participaram do ato golpista serão punidos. Todos. Não importa a patente, não importa a força que ele participe. [Everyone who participated in coup activity will be punished. Everyone. No matter what rank, no matter what branch of the military they're in.]"

Lula relieved Arruda of his post as commander of the army on 21 January 2023, replacing him with Tomás Miguel Ribeiro Paiva.
