 Gunfire was reported near Camp Shelby on two straight days; no one was injured 
 
 (CNN) Mississippi authorities have arrested a man in connection with recent reported gunfire near the Camp Shelby military post -- though he hasn't admitted to shooting at anything, a local sheriff said Wednesday. 
 
 This comes after two incidents of reported gunfire near the southern Mississippi base, one on Tuesday and another in the same area around 8 a.m. (9 a.m. ET) Wednesday, according to Mississippi National Guard spokesman Lt. Col. Christian Patterson. No one was injured in either case. 
 
 Afterward, Perry County authorities and the military launched a hunt for whoever fired the shots, described in both cases as a white male in a red pickup truck, Patterson said.

 Exportable Combat Training Center (XCTC) exercises will begin this Saturday at Camp Shelby and last about three weeks. 
 
 A controversial, two-month-long Army training exercise called Jade Helm 15 started Wednesday in seven states, including Mississippi. 
 
 The Army has not given any specifics about Camp Shelby's role. 
 
 Some fringe websites suggest Jade Helm is laying the groundwork for martial law. 
 
 But, the Army said the public will see little disruption during the training. 
 
 Meanwhile, thousands of military personnel are about to participate in a another training exercise separate from Jade Helm that's a first for Camp Shelby. 
 
 Solders from the Mississippi National Guard's 155th Armored Brigade Combat Team, along with active-duty troops from different branches of the armed forces, will take part in Exportable Combat Training Center (XCTC) exercises beginning this weekend. 
 
 
 
 Mississippi National Guard officials said the goal of the exercise is to demonstrate how well National Guard, Reserve and active-duty forces can work together. 
 
 "It will start on the 18th with the 1st Battalion of the 155 (ABCT), they'll start doing their gunnery," said Maj. Gen. Augustus Collins, adjutant general for the State of Mississppi. "That will be the first actual training event that we'll kick off with, but we're going to run this exercise for the next three weeks and we're going to stagger units from the 155th Brigade in." 
 
 Collins also said many high-ranking government and military leaders will be visiting the post to observe the training.

 Lt. Colonel Patterson said thanks to a recent order from Governor Bryant, guards at all base entrances were armed. "Everybody out there can rest assured that our security is enhanced. It's something that we take very seriously and that we look at constantly in order to ensure that it's strong," said Patterson.

 One person is in custody in connection to an investigation outside of Camp Shelby 
 
 A press conference was held Wednesday afternoon regarding the two incidents near Camp Shelby. Earlier Wednesday,Baria, 61, drove a maroon truck past authorities when they thought they heard another shot. Authorities pulled over Baria and took him into custody for questioning. 
 
 Baria admitted that he was the person that police were looking for in connection to the incidents. Baria claimed he did not fire any shots, and that the sound authorities and soldiers heard was just his truck backfiring. 
 
 ATF found two guns at the suspect's home. Biloxi Bomb Squad did find a device in the suspect's truck, but confirmed it was not dangerous. 
 
 Perry County Sheriff Jimmy Dale Smith confirmed during the press conference that they were still interviewing the suspect. 
 
 There is no confirmation at this time if the suspect fired a gun. Greg Michel, installation commander at Camp Shelby, confirmed that the incident did not happen on Camp Shelby grounds, but just outside the facility on Paret Tower blacktop off Highway 29. 
 
 Michel also said that soldiers did claim of hearing gunshots, but never saw a gun or any shell casings. 
 
 The investigation has now been handed over to Mississippi Bureau of Investigation. 
 
 The investigation is ongoing and there is no confirmation as to whether the incident involved was a shooting at all. 
 
 The scene Wednesday morning: 
 
 According to The Department of Defense, at approximately 8 a.m. Wednesday morning, soldiers reported what they thought were gun shots being fired again at Camp Shelby. 
 
 This is the same area where soldiers reported gunfire from a motorist at approximately 11:45 a.m. on Tuesday. 
 
 The Camp Shelby Joint Forces training center immediately went into a heightened state of alert. No service members have been hurt or injured in either incident. The post is secure and all personnel are accounted for.

– Routine military exercises at Camp Shelby in Mississippi weren't supposed to be this intense: For the second straight day, shots have been fired near the camp in Hattiesburg, reports WDAM. Again, nobody was injured, and the description of the shooter is similar: white male in a red or maroon pickup. "We're making sure soldiers are aware of what's going on so they can take the proper precautionary measures," says Lt. Col. Christian Patterson. Today's gunfire took place about 8am near a checkpoint just outside the base, reports CNN. One person has been detained for questioning, notes WDAM. Speculation as to motive differ: It's possible it could be an oblivious hunter, but the camp will be in a "heightened state of alert" until authorities figure out what's going on, reports the Clarion-Ledger. The base is conducting something called the Exportable Combat Training Capability exercise involving about 4,600 soldiers from the 155th Armored Brigade combat team and other National Guard and Army Reserve units. That exercise is not the same as the Jade Helm training going on in several states that has conspiracy theorists worries about martial law, notes WDAM. The Army has not offered any specifics on the camp's role in Jade Helm, notes the station.
