‘It’s either kill or be killed’: the South Americans going to fight in Ukraine

"Mission accomplished," shrugged the Brazilian army reservist. "In war, it's either kill or be killed."

"If I get someone in my crosshairs and don't shoot, he might shoot me. It's just like a game of paintball," he added, as the mid-morning sun bathed his home in north Rio.

From Brazil and Argentina to Mexico and Colombia, volunteer fighters have voiced interest in joining - or already joined - Ukraine's international legion for what they describe as a mix of ideological, humanitarian and financial reasons.

The volunteers range from battle-hardened veterans of Colombia's US-backed "war on drugs" to Argentinian students who have never picked up a gun and Brazilian Instagram influencers who have been criticised for putting lives at risk by using the conflict as clickbait.

Ukraine's president, Volodymyr Zelenskiy, announced the legion's creation three days after Russia's 24 February invasion, telling would-be fighters: "Please come over, we will give you weapons."

Uriel Saavedra, a former member of the Colombian police unit that protects government officials and VIPs, said he hoped to reach the battlefield within a fortnight after signing up to fight through a Colombia-based security firm.

"If someone wants me to go to war in Ukraine, well, obviously they're going to have to pay - because the risk of coming back dead is so high," said Saavedra, 40, who expects to receive $10,000-a-month from the company which recruited him and about 30 other veterans.

Saavedra, who saw the job advertised on a WhatsApp group for military and police veterans, recognised it was dangerous. "But we're prepared. We can use any weapon they give us," said the soldier of fortune who sees the war as a way of supplementing his $1,000-a-month state pension.

Boa Morte said his son was horrified. "Damn it, Dad, are you nuts?" he had asked. But the reservist was determined to travel, despite concerns about sub-zero temperatures. "We'll be so full of adrenaline when we arrive we won't notice the cold," Boa Morte said as he sat beside a swimming pool in a Rio sports club wearing flip-flops and shorts.

Some Latin American legionnaires have already reached Ukraine, among them Tiago Rossi, a shooting instructor from south Brazil who claimed he had set off for his first war in early March, one day after turning 28.

Rossi, who said he was accompanied by two other Brazilians - a former infantryman and a former paratrooper - recalled meeting combatants from South American countries including Argentina, Chile and Colombia, whose mercenaries are coveted by contractors because of their experience fighting leftist rebels, paramilitaries and drug traffickers.

But how such bravado will hold up in the face of the horrific realities of Ukraine's conflict is unclear. Rossi said he had retreated into Poland after Russia bombed the Yavoriv military base where he was staying. He said he had no plans to return and would instead seek to help South Americans in Polish refugee centres. "I think I'll be more useful here than over there [in Ukraine]."

Many of the Brazilian volunteers appear to be disciples of Brazil's far-right president, Jair Bolsonaro, a former paratrooper who is popular in the military rank and file. But Bolsonaro, who visited Moscow on the eve of Russia's invasions and has seemed to take Putin's side, has outraged some followers with his stance.

Emilio Galdeano, a retired shooting range owner, said he was too old for combat but supported his son, despite fearing for his safety. "If he was a kid I'd tie him to the foot of the bed and give him a bit of a hiding with my belt. But he's too old for that," he sighed.
