The 12th Light Infantry Brigade (Airmobile) (Portuguese: 12.ª Brigada de Infantaria Leve (Aeromóvel), 12ª Bda Inf L (Amv)) is a large unit of the Brazilian Army based in Caçapava, São Paulo.

Since 1995 its elements have been transported by Army Aviation helicopters, being able to quickly operate in any part of Brazil's territory.

The brigade has participated in several political-military events in Brazil's history, and some of its personnel was part of the Brazilian Expeditionary Force in World War II, giving rise to its name "Brigada Fornovo di Taro" (Fornovo di Taro Brigade) in honor of the homonymous battle.

At the beginning of the 20th century, the reorganization of the Brazilian Army in the Old Republic created several infantry brigades within the new divisions.

[3] After two command predecessors, first in Mato Grosso do Sul and then in Minas Gerais, the 4th Infantry Brigade was formed in Caçapava in 1919.

[4] It consisted of the 6th Infantry Regiment (RI), at headquarters, and the 4th, 5th and 6th Battalions of Caçadores (BCs), respectively in São Paulo, Lorena and Ipameri.

[22] In 1926, amid the expectation of a federal intervention in Goiás, several testimonies attested that a platoon from São Paulo reinforced the 6th BC in Ipameri.

[24] In the Revolution of 1930, the 4th BC was among the loyalist forces on the border of São Paulo and Paraná, acting in the regions of Quatiguá and Itararé.

[4] In World War II, the 6th RI was one of the three infantry regiments to integrate the Brazilian Expeditionary Force, arriving in the Italian campaign in the first echelon of the FEB, in July 1944.

[32] Zerbini managed to delay, but failed to prevent the participation of the 5th and 6th RIs in operations in the Paraíba Valley.

[34] In 2018, the brigade contributed approximately 450 men in rotation to the federal intervention in Rio de Janeiro[35] and acted on the highways of São Paulo during the truckers strike.

[36] In conjunction with the U.S. Army's 101st Airborne Division, Task Force Itororó of the 12th Brigade participated in the "Core 21" exercise in the Paraíba Valley in 2021.

[37] Positioned in the central core of the country and with rapid displacement, the brigade is part of the Brazilian Army's strategic reserve.

[44] Its garrison in Lorena has already been described as a "key point of communications between Rio, São Paulo and Minas Gerais".

They must occupy weakly defended positions in the enemy rear, where they control an airmobile bridgehead until other forces arrive.

[53] The brigade's infantry has smaller and less heavily armed light rifle platoons than paratroopers, possibly due to the helicopters' carrying capacity.
