The six are army soldiers whose ranks range from sergeant to chief warrant officer attached to a military camp in Kanchanaburi province.
They are to be charged with attempted murder and illegal possession of firearms.
A letter has been sent to inform their respective units that warrants have been issued and approved for their arrest and for them to hand over the six to the police for legal proceedings.
A suspect, identified as Matuemang Mase of Narathiwat, had earlier been arrested in connection with the shooting. The man allegedly claimed he was hired by three soldiers attached to a military unit in a western province.
On Saturday, he performed a re-enactment of the crime in Udon Thani.
