The troops will work with engineering units on the construction of the so-called East Shield, a Polish defence programme that includes fortifications as well as drone and counter-drone systems, Kosiniak-Kamysz said.
He added that about 80 French military engineers would join the Polish forces working on the project.
"The East Shield is no longer a national project; it has become an allied project," Kosiniak-Kamysz said at a news conference marking two years of the programme.
He noted that German military engineers were already helping with the construction and said more NATO allies would soon join the effort.
The East Shield covers Poland's borders with Russia's Kaliningrad exclave, Belarus and Ukraine. Its aim is to strengthen Poland's ability to defend its territory and deter a potential adversary.
Kosiniak-Kamysz said about EUR 10 billion had already been allocated to measures aimed at securing Poland's eastern border.
He said the programme was reaching initial operational readiness in many locations after two years.
The defence minister also announced plans to develop an operation dubbed "Eastern Sword" aimed at strengthening deterrence through long-range precision strike capabilities.
"Long-range precision strike and strategic strike capabilities are key to the security of the Polish state," he said.
Kosiniak-Kamysz credited the European Union's SAFE defence financing mechanism with helping expand the East Shield programme, saying it had enabled nearly 30 additional projects.
Those projects include drone and counter-drone systems, artificial intelligence and cyberdefence capabilities, he said.
Kosiniak-Kamysz also thanked the EU for recognising the East Shield and Baltic Defence Line as strategic security programmes and the United States for including the East Shield among programmes aimed at strengthening Europe's security.
The defence ministry said the East Shield was also being used to test new technologies.
Deputy Defence Minister Cezary Tomczyk said the "Smart Border" programme was testing robotics, unmanned systems and artificial intelligence.
Lt. Gen. Stanisław Czosnek, deputy chief of the General Staff of the Polish Armed Forces, said the war in Ukraine had demonstrated the importance of drones, sensors, fortifications and the ability to rapidly adapt to changing battlefield conditions.
"Poland is using this direct transfer of operational knowledge, but we are not copying it one-to-one," Czosnek said.
"We are trying to adapt it to Poland's geography, the structure of our armed forces and our domestic and NATO operational plans," he added.
Kosiniak-Kamysz also announced a PLN 1.5 billion (EUR 350 million, USD 410 million) funding competition for healthcare facilities, including hospitals in northeastern Poland.
The money will be used to expand infrastructure protecting residents and supporting the military's ability to provide care for soldiers, he said.
The projects will also include helipads, rapid-response centres and emergency and rescue facilities, Kosiniak-Kamysz said.
The East Shield is part of Poland's broader effort to strengthen its eastern border and military capabilities amid heightened security concerns following Russia's full-scale invasion of Ukraine.
