Who would the man in the field be today in modern terms?

That figure represents today's working-age, working-class people. In modern terms, he would likely be a computer operator, office worker, stockbroker, or similar worker. Such people are told to drop their work and flee quickly without returning for an extra suit of clothes.

Les explains that verse 18’s man in the field is part of a cross-section of Jewish society, not the 144,000, fleeing Jerusalem after the Antichrist defiles the temple and turns on the Jew. In Christ’s day Israel was an agrarian nation, so the field worker represented working-age, working-class people. Les says the modern equivalent would probably be computer operators, office workers, stockbrokers, and similar occupations. Whatever their work, they must drop it and get out fast, not even going back for an extra suit of clothes.

Matthew 24:18

Neither let him which is in the field return back to take his clothes.

Who are the modern equivalents of the man in the field in Matthew 24:18?

The modern equivalents are working-age, working-class people such as computer operators, office workers, and stockbrokers. In Christ's day Israel was agrarian, so the man in the field represents laborers. Today, whatever their work, they must drop it and flee quickly, not returning for clothes.
