Warsaw, Poland - They may look like lost tourists - fluffy and equipped gear - or hikers with military hairstyles, survival gear, and don't know how to perform in the woods.

But Latvian intelligence agencies said on Wednesday that they could actually be Russian sabotagers and spies.

Latvian acronym MIDD famous Latvian Defense Intelligence and Security Services provides advice on how to identify potential reconnaissance and sabotage agents in its annual report.

Given regional tensions, a series of arson and other acts of vandalism, this is an increasingly relevant concern that Western governments blame on allegations that Russia-Moscow has repeatedly denied.

The list of Telltale logos is shocking: poor appearance, military mismatch or sportswear mismatch, and tricks to doubting locals. According to the Security Agency, such groups may linger near military or critical infrastructure locations, posing as humanitarian workers or staying in remote areas without showing any interest in nature.

Some people may carry a dedicated medical kit, map or radio – a better suited for covert operations than camping trips.

Latvia's guidance is the country in the region, including new members of Sweden, including Sweden and Finland, who have been publishing advice to brochures on how to survive wars or natural disasters.

Nearby Poland is now preparing a guide, while Norway recently published a book with advice on how to survive for a week.

"We live in an increasingly turbulent world," it says. "Even in Norway, most things usually work as usual, but we must realize that extreme weather, pandemics, accidents, destructiveness, and in the worst acts of war can affect us."

MIDD, one of Latvia's three security services, along with the National Security Service and the Constitutional Protection Agency, warned that Russian saboteurs may also try to incite unrest or assassinate "people of social significance."

Their activities may also focus on “studying the status of the society of the target country and inciting unrest against existing governments.”

The agency warns that appearances can be deceitful.

"Ukrainian experience shows that Russian special services can adapt." Not all spies will fit into molds and doubts must be judged in the context.

It also warns that if a destruction group is found, leave the hero of James Bond to the professionals.

"If you do think you may have found a destructive group on Latvian soil, then MIDD does not recommend you resolve it yourself," it said. "But report your suspicion to the state police, special services or recent armed forces."
