8:38 | 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.

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.
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.
Back in the States and commanding a Signal Battalion, engineer Mac McCahan wrote an article on nodal communications systems that was groundbreaking. He used off the shelf gear and existing installations and improved service for all users.
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.
After his last tour in Korea, Jim Bolan was assigned to Special Forces. No volunteering needed. Everything was highly classified and they began training with no real system in place. Different units were then combined to form the 1st Special Forces Group, based on Okinawa.
It was a lousy assignment. Jim Bolan was one of the first Special Forces officers and, after Vietnam, he wound up in a training unit with no jump slot. Prodded by his wife, he went to Washington to dust off his most valuable inside contact, who was now the Army's Chief of Staff.
After his Vietnam tours, Jake Jacobson served in Thailand and the Philippines, among other places, with different Special Forces teams. After almost thirty years of service, he retired, but was soon in Saudi Arabia training Bedouins. He didn't care for that job. (Caution: coarse language.)
Bob Stewart was more nervous going to Vietnam than he was going into space the first time. You could get maimed in combat but in space you were either A-OK or completely gone. He made two flights on the space shuttle and, along with Bruce McCandless, made the first EVA with the new MMU, the Manned Maneuvering Unit.
Lt. Geoff Farrell was sleeping in the command track when he heard it on the radio. We were at war with Iraq. His armored cavalry unit crossed from Saudi Arabia into Iraq where they were greeted by friendly children in the middle of nowhere.
Bob Stewart arrived in Houston as the first active Army officer to become a space shuttle mission specialist. After a year of classes, he was given a technical task, develop the shuttle's entry flight control system. The first flight was scheduled for two years out but he had to give management some bad news.
After the battle, the men of the 2nd Armored Cavalry did humanitarian work for the Iraqi civilians, then it was time to return to Germany. For Geoff Farrell, a feeling of unreality set in on the flight home. How do you decompress from combat? At least those who fought in this war were not going to experience the humiliation that Vietnam veterans had faced.
When the cease fire was declared, American units had not yet reached Baghdad. In his command track, Geoff Farrell had the graphics on his screen to guide him right in, but it was decided we would not go. Looking back to that critical moment, he reflects on the decision.
Bob Stewart was walking on air. He just got a call from NASA that he was accepted as a mission specialist on the space shuttle program. He was going to be an astronaut, but first he had one more flight in his capacity as an Army test pilot.
Returning Marine Norman Kling had his eye on college when he got home from the Pacific. He entered the electrical engineering program at Washington University in his home town of St. Louis. He had a soft spot for the Corps in his heart or maybe it was his head. Either way, he joined the Marine Corps Reserve.
After the Challenger tragedy, NASA mission specialist Bob Stewart returned to the Army where they made him a general. He worked at the Strategic Defense Command, a legacy of Ronald Reagan's SDI program. At some point the Army wanted him in Washington DC, at which point he promoted himself to ski bum.
They had prepared for the wrong war. Geoff Farrell's armored cavalry unit was going to the desert to confront Saddam Hussein, but their vehicles and uniforms were green and all their training was for fighting in European forests. Once they got to the staging area in Saudi Arabia, they adapted well.
During Operation Just Cause, John Le Moyne was assigned to the Joint Special Operations Command (JSOC) as a liaison officer to other agencies. In this capacity, he was able to observe some high level command operations that were very impressive. It was only a short while after this brief conflict that Saddam Hussein began to make noise in the Middle East.
He was free. Bob Ratonyi had made it out of communist Hungary into Austria. His first stop was a refugee camp, which was overcrowded. He made it to Vienna with the help of a Catholic charity and, once there, he made straight for the American embassy. Unfortunately, the quota for refugees had been met. He had three choices, Australia, Sweden and Canada.
His time with the 1st Cavalry Division at Fort Hood was the best time of his Army career. Bill Greinke bested a well known commander in a war game and he went on splendid maneuvers in Europe at the Fulda Gap. Then he moved on to specialized training in media and information.
John Le Moyne had come in to Saudi Arabia leading an advance team. Starting from scratch in the desert, in the summer, huge operating bases were established. The locals were amazed at the way the Americans adapted to the environment. It was during this conflict that many innovations in troop care and comfort were devised.
He considered it the finest education available. Geoff Farrell went to West Point, where he soaked up all the history and knowledge available there. He was assigned to Europe, where he patrolled the German border as Soviet Communism was dying. There was a brief period of jubilation when the wall came down, then they heard about Saddam Hussein.
John Le Moyne never had a bad assignment. That's the way he looked at it, anyway, and it had a lot to do with the excellent leaders he encountered throughout his career. They helped him crack the code on how to win the trust of soldiers.
The rumor was that the Iraqi's Soviet made tanks were superior to ours. Geoff Farrell had this on his mind while rolling across the desert to engage them. Just as they got near, a sandstorm came up. Then the Iraqi artillery began to fall. Then the first Iraqi tank was destroyed, shattering the myth.
