Could create a new nation by combining all South American vehicles, as many of these vehicles come from different places and eras. For example, in Brazil, from 1944 to 1970, there were many American vehicles, such as:
Light Tank M3 Stuart: The M3 Stuart tanks were used by the Brazilian Expeditionary Force (FEB) in the Italian Campaign.
Medium Tank M4 Sherman: Brazil also used M4 Sherman tanks, which were versatile combat vehicles widely employed by the Allies.
Reconnaissance Car M8 Greyhound: The M8 Greyhound was an armored reconnaissance vehicle used by Brazilian forces in Italy.
Half-track Troop Transport M3 Half-track: These vehicles were used to transport troops and equipment.
From 1970 to 2000, German vehicles:
Leopard 1 Tanks:
The Brazilian Army acquired Leopard 1 tanks from Germany in the 1970s. These tanks were used as main combat vehicles for many years and were modernized over time to maintain operational effectiveness.
Eurocopter EC725 Cougar Helicopters:
Although not a ground vehicle, it’s noteworthy that Brazil acquired EC725 Cougar helicopters, manufactured by Eurocopter, a European company with German influence. The EC725 is used in various functions, including troop transport and search and rescue.
Wheeled Armored Vehicles (VBTR) Mowag Piranha:
Brazil acquired wheeled armored vehicles Mowag Piranha, produced by the Swiss company Mowag, which is part of the German group General Dynamics European Land Systems. These vehicles are used for troop transport and have versions adapted for different purposes.
Thus, it is difficult to decide whether the vehicles should be attributed to the United States or Germany. This also applies to other Latin American countries, like Peru, which had from 1940 to 60.
T-26 and BT-5:
During the 1940s, Peru acquired some light tanks, such as the Soviet T-26 and BT-5. These tanks were used for patrol and defense purposes.
Sherman M4:
After World War II, Peru acquired Sherman M4 tanks from the United States.
M3 Stuart:
Peru acquired light tanks M3 Stuart during the 1940s.
M4 Sherman:
Medium tanks M4 Sherman were used by Peru, mainly acquired after World War II and throughout the following decades.
M24 Chaffee:
Peru also incorporated medium tanks M24 Chaffee, which were light and agile vehicles used in various roles, including reconnaissance.
M41 Walker Bulldog:
In the 1960s, Peru acquired medium tanks M41 Walker Bulldog, a more modern and agile version, to replace some of the older models.
M551 Sheridan:
The M551 Sheridan, an amphibious light tank, was also acquired by Peru.
From 1970 to 2000:
During the 1970s and 1980s, Peru acquired T-55 and T-72 tanks of Soviet origin. These acquisitions were part of the modernization efforts of the Peruvian Armed Forces during that period.
Due to this, it would be better to create a new South American nation. A single Latin American country by itself would not be truly justifiable, but several smaller-sized countries would be more suitable.
