A driver attempted to run over soldiers as they were jogging in southern France.
The soldiers, who belong to the 93rd Mountain Artillery Regiment, avoided the vehicle in Varces-Allières-et-Risset near the city of Grenoble.
French Army spokesman Colonel Benoît Brulon said the man had "verbally threatened" the troops as they left their barracks, before trying to ram them as they returned.
"The soldiers managed to get up onto the pavement without being hit", Brulon said.
Quoted by the newspaper, the public prosecutor in Grenoble, Jean-Yves Coquillat, said that "we must remain cautious regarding the motives of the attacker".
