Henry's blatant mockery did not provoke any displeasure or brotherly sentiment from Jack Reacher. The reason was simple: everyone here belonged to the U.S. Army, while he alone was military police, specifically tasked with overseeing the Army.
Not to mention the difference in rank. One was a military police major, while the other two were merely enlisted men, not even officers. The escort officer and NCO were still sitting in the vehicle like they owned the place.
This was like street punks running into a patrol officer. Under normal circumstances, neither side would call the other brother. Naturally, the patrol officer would not shamelessly try to mingle with those little street thugs, either. The fact that they had not started fighting on sight was already remarkably restrained.
Still, Henry picked up some important information from Jack Reacher's words.
First, General Thaddeus Ross knew that Tony Stark had secretly investigated the cause of the Starks' deaths. He might even have been the one who authorized Jack Reacher's transfer to carry out an investigation that was practically a private matter.
Whether it was Tony Stark's commission or the deaths of Howard Stark and his wife, neither was something the military could openly acknowledge. Even if records existed, they would surely carry a certain level of classification.
Provided his clearance was high enough, General Thaddeus Ross had the authority to view the original classified documents without redactions.
Unless he had been paying attention to Henry Brown for a long time, if he only decided to investigate his background because of this incident, the relevant files might still be stuck in the declassification request stage. He would never have thought to send Jack Reacher.
Besides, Jack Reacher was a highly disciplined soldier. He would not accept this kind of private commission without formal orders.
