When communications engineer Mac McCahan arrived in Vietnam, he had to straighten out an Air Force Colonel who was trying to send him to Thailand, where he wouldn't get credit for a combat tour. Then he settled down to improving voice communications and found out that it was so stressful on the switchboards, operators were committing suicide.
"We don't want your equipment!" Communications engineer Mac McCahan was trying to improve military telephone service in Vietnam and he had to repeatedly reassure units that he wasn't tying to take over, just trying to make the system work better.
They wouldn't tell Mac McCahan who the visitor was, but they told him how many voice circuits were required and that the restoration priority on those lines was "1b." That got his attention because that was the code for President of the United States.
Mac McCahan lost two cousins in Vietnam, Lee and Gene McCahan. If that wasn't bad enough, his brother George McCahan died from leukemia due to contact with Agent Orange. His own luck stayed with him, though, and he kept missing enemy ambushes by thirty minutes.
Mac McCahan never cared for the rule that he had to store his weapon in the safe in his office. When the Tet Offensive happened, he had to hunker down, unarmed, in his quarters. When he returned to the States, he was armed only with his dignity as he faced rabid protestors.
Mac McCahan felt like he was doing something great on his second tour in Vietnam. As he transferred control of facilities to the Vietnamese, each one meant that soldiers were going home. Then he stopped at the dispensary to find out why he was suddenly soaked in sweat. Part 1 of 3.
While the doctors tried to find out whether he'd had a heart attack or not, alarming telegrams began to go out to Mac McCahan's family, despite the fact that he'd signed a document directing the Army to send such messages only in the event of death. Part 2 of 3.
The doctors still didn't know if he'd had a heart attack or not, but they sent Mac McCahan home from Vietnam, regardless. Then they told him he was on his way out of the Army. "No. I'm not," came the reply. Part 3 of 3.
Mac McCahan knew he wanted a military career. He had a taste of military life as an Air Force dependent and he secured a congressional appointment to the Air Force Academy, but a run in with an eye chart derailed that. He settled in at Clemson with Army ROTC but a freak accident cost him a year.
Mac McCahan's first assignment in the Signal Corps was in Germany, which was just what he wanted. His wife could experience some of what he enjoyed as a military dependent stationed there. When the Berlin Wall crisis came up, it turns out he had the only American cable splicer in Europe.
In the post-Trujillo chaos of the Dominican Republic, Signal Corps officer Mac McCahan began a long run of finding solutions to communications problems. After restoring phone service by adapting old exchanges, he was able to communicate with Washington by whistling the appropriate tones to establish a connection.
As if restoring communications in the restive Dominican Republic wasn't enough to keep him busy, Mac McCahan had to deal with constantly shuttling back to Ft. Bragg for briefings and an acting Signal Officer who wrote him up for spite. Not to mention lacking the counter sign at a crucial time.
After his tour in the Dominican Republic Mac McCahan began the Training With Industry program. He worked with the New York phone company learning the network and installing phones in the field, then applied that knowledge to military telecommunications.
Communications engineer Mac McCahan caught the eye of the White House when he successfully managed two projects for the White House Communications Agency. The first was extending coverage of the first moon landing to Alaska and the second was managing the satellite link for a presidential trip to Asia.
"This is all classified. I recommend it not be broadcast." That's what Mac McCahan had to say about a script for an upcoming CBS news program. Three weeks later, what did he see when he turned on the television?
The signal battalion was ecstatic when they got in any new gear following the Vietnam war, remembers Mac McCahan. Nearly everything had been left there. In order to jump with communications capability at hand, he crammed a Command Post's worth of radio gear onto an Army Mule cargo vehicle. And what do you call a Mule full of radios?
Assigned a command position that was usually occupied by a Lt. Colonel, Major Mac McCahan sought assurances that he would get no interference because of his rank. He got that assurance and soon, the promotion to Lt. Colonel as well. Then he wound up with a distinctive blue beret thanks to the new Air Assault movement.
Reorganization was swirling around Mac McCahan at the 101st Airborne and he was nearly made battalion commander. After a European exercise where he met two Medal of Honor recipients, he found out that a communications plan for a hospital he'd drawn up had achieved some distinction.
Mac McCahan relates the story of a Chinook that mistakenly strayed into the Korean DMZ and was shot down. Closer to home, as North Korean armor was massing across the border, he tells why his wife became suddenly upset and convinced that another war was imminent. It turned out to be a case of Loose Lips.
Leaving Korea with his family and adopted daughter was a struggle. Striking airlines and visas gave him fits but they made it home and he eventually became an advocate for Amerasian adoption, appearing before Congress to support the cause.
His expertise in satellite communications landed Mac McCahan a position at the headquarters of the Joint Chiefs of Staff in Washington. That expertise was put to good use on an ill fated mission during the Iran Hostage Crisis.
There was no doubt Mac McCahan was a problem solver. He developed a scheme for bit stuffing that made incompatible gear work together. Should have been a patent right there. Then he encountered a problem that was projected to cost one million dollars and take a year to fix. Would he do it in half the time for half the money? Think again.
The Generals kept asking, why do we lose our satellite link during the heavy tropical rain in the Philippines? The answer, according to communications engineer Mac McCahan, is in the true shape of a raindrop, a shape which is not what you might think.
Mac McCahan has a message for all who served in a support role instead of a combat unit. First, consider yourself lucky, and second, your service was just as necessary and contributed just as much as anyone's.
Bill Pearson had been to Vietnam twice and returned unscathed, but the Army wasn't done putting him in danger. He was assigned as an aviation consultant to Iran, advising the Shah's air force on it's supply of American aircraft. The day he arrived, martial law was declared and it wasn't long before there were mobs outside trying to burn down the building. The embassy was no help. Escape seemed impossible.
His aim was to help put his sister through college. Walt Richardson scored so well on the tests that he was inducted into the Air Force. Perhaps it was the schooling he received at the school run by the mother of Chappie James, who became the first black Air Force 4-star General.
For Walt Richardson, it was all about the core values of America. As one of the first black airmen to integrate the Air Force, he calls on his unique perspective to explain why America is so much greater than other nations that are so much older.
He had been a glider pilot in the war and he was a bona fide power pilot who could fly many smaller planes. George Theis then became a flight engineer in a B-52 unit. He was in the cockpit readying for a flight when the pilot asked if he'd like to try a take-off.
Army surgeon Quinn Becker almost retired but he was selected to attend the War College. That usually meant they were grooming you for higher up. As he moved up to higher commands, he set out to modernize antiquated field medical equipment, a need he had first noticed years before.
When George Theis returned from occupation duty, he got married and began seeking a career in civilian aviation. The tough job market drove him back into the newly renamed Air Force. He had a good run as a flight engineer and worked on the conversion to computerized controls.
After successfully completing aircraft mechanic school, Walt Richardson joined the crew on a commanding general's B-17 in Okinawa. As the only black crew member, he had to earn respect and he did. He was also part of the honor guard when the first freely elected leaders in Japan were inaugurated.
Walt Richardson was in the last all black training flight in the Air Force. His aim was to serve his three year obligation and then return to college, but he saw a musical revue put on by members of the fabled Tuskegee Airmen. They were holding open auditions and he went to showcase his fine singing voice.
The 18th Field Artillery Brigade supported a lot of units during Operation Desert Storm, including the French Foreign Legion. Should the war have continued on into Baghdad? Going home was OK with Freddy McFarren. He had already been in the desert for eight months.
When an alert was sounded, the procedure for fighter pilot Rick Hilton was to get his aircraft fueled and wait at the end of the runway with a live nuclear weapon on board. Someone thought this was a little too much power for a fighter jock so the procedure was changed to include blocking the taxiway with a fuel truck. Then a real alert came in.
He was only four years old when Rick Hilton's uncle let him "fly" his airplane. The kid couldn't reach all the controls but he did get a deep desire to fly. He got his chance in college with the Air Force cadet program and was soon piloting jet fighters.
It was a very difficult program to get into, but Marvin Cole persisted and was one of the final candidates standing to be admitted to the Army's physician assistant training program. After that, he was sent to Germany where his management ability got him noticed.
After being an advisor in Vietnam, Freddy McFarren returned to his first love in the military, artillery. As a commander with the 82nd Airborne, he fired some of his guns in Grenada. That operation convinced him and others that the military needed to increase joint operations training.
It was a busy four days in Iraq for the 3rd Brigade Combat Team commanded by Bob Clark. Once the cease fire was declared, his mission became more humanitarian with swarms of displaced persons to take care of. Then there was that Elvis sighting.
He never even thought about getting out. Freddy McFarren liked the Army because of the people, quality people at all levels. His long career eventually saw him return to West Point, where he helped prepare the next generation of leaders.
When Bob Clark arrived to assume command of the 3rd Brigade of the 101st Airborne Division, Saddam Hussein had just moved into Kuwait and the unit was preparing to deploy. Soon, he was staring across the Saudi desert into Iraq.
Lawson Magruder, who commanded troops in the Somali deployment, was disturbed by what he discovered after the conflict was over. Partisan distrust following a change of administrations had sidelined the most experienced diplomat in the area. This contributed to an already bad situation.
