Riding on motorcycles and in pickup trucks, the protesters traveled in a noisy parade to seven locations including the Bangkok zoo and Buddhist temples being used by soldiers as temporary camps.
Some of the soldiers packed their belongings and left to avoid clashes, drawing raucous cheers from the protesters, who are entering their third week on the streets of the capital.
"We will storm the places where soldiers camp out. We'll shake the fence. We'll cut the barbed wire. We'll march through the barricades. We'll march for democracy!" a leader of the "Red Shirt" protesters, Nattawut Saikua, shouted to the crowd. "This is where we'll end military suppression. This is where we'll create democracy."
Prime Minister Abhisit Vejjajiva has called in thousands of troops to guard Parliament, government buildings and other key locations amid fears of violence. Protesters have denounced the show of military force as unfitting for a democracy and said their goal is to peacefully pressure the soldiers to return to their barracks.
However, Saturday's protest took a more confrontational stance than previous rallies.
The protesters accuse Abhisit of taking power through illegitimate means with the support of the military and are demanding he dissolve Parliament and call new elections, which he has repeatedly rejected. Abhisit has been sleeping and working from an army base since the protests started March 12.
"It is not our aim today to use violence. We'll be visiting these soldiers as friends," said another protest leader, Veera Muksikapong. "They would know that we come in good will." Leaders of the protest movement - formally known as the United Front for Democracy against Dictatorship - have increasingly portrayed the demonstrations as a struggle between Thailand's impoverished, mainly rural masses and a Bangkok-based elite impervious to their plight.
