From AmmoLand, Candidate Trump:
"They will be able to defend themselves against terrorists. Our brave soldiers should not be at risk because of policy created by civilian leadership. Political correctness has no place in this debate."
That policy was reiterated in 2018. President Trump said he would review the policy of keeping service members disarmed on our military bases and recruiting centers.  From military.com:
President Donald Trump said Friday that he would review policies that keep troops from carrying personal weapons onto military bases.
In spite of this promise, highly trained and motivated aviators were killed by a terrorist at Naval Air Station (NAS) Pensacola, Florida, on 6 December, 2019. Several were wounded. All were unarmed by DOD and Naval policy. While NAS Pensacola has a security team, they were ineffective in stopping the terrorist at the base:
He says this group is comprised of active-duty sailors and individuals from the department of Naval citizens. He says these are the only armed personnel on the base, all other firearms are banned.
