   Avoiding 'Friendly Fire.' Army Drags Feet Over a New System.

   By John Mintz


   In 1991 the Army, appalled by American soldiers
   accidentally shooting fellow troops in the Persian Gulf
   War, declared efforts to prevent "friendly fire" a top
   priority.

   But today, the Army is delaying installation of a
   promising, 3-year-old electronic technology that has proved
   repeatedly in tests to help end such fratricidal incidents
   among tanks and other armored vehicles, according to
   military officials, members of Congress and defense
   industry executives.

   Army officials agree the new equipment is effective at
   allowing U.S. combat units to identify one another quickly
   and silently in battle. But they say they do not have the
   $300 million or so to put it on most tanks and other
   armored vehicles, even as they are planning to spend
   billions in coming years to upgrade such weapons in other
   ways.

   Some retired military officers and industry executives say
   the Army has lost some of its zeal in ending combat
   fratricide and would rather spend money on increasing its
   weapons' combat capability.

   The Army is "slipping back into a position it's had for
   decades, that fratricide is just a small problem," said
   David Sa'adah, who retired as a colonel last year and was
   a longtime Army expert on friendly fire.

   The Army strenuously denies such allegations. It has
   ordered further tests for the new equipment and Army
   officials say they are seeking to reduce fratricide through
   improved training, battlefield doctrine and technology.

   But the service is coming under pressure from Congress to
   move more quickly to install the technology, known as the
   Battlefield Combat Identification System, or BCIS. The
   system allows a weapons system to "question" another
   electronically as to whether it is American, and to receive
   an answer in a tenth of a second.

   The House National Security Committee favors immediate
   fielding of BCIS. It said in a recent statement it "finds
   it difficult to understand the Army's delay in initiating
   procurement." The committee noted under current Army plans,
   the earliest BCIS could become available for troops is 2000
   and other people guess 2003.

   Concern over "friendly fire' soared with the Persian Gulf
   War, when 35 American troops were killed by fellow soldiers
   out of 146 dead, or 24 percent -- the highest recorded rate
   for Americans in a war. Also troubling were the low-tech
   tactics troops were forced to use to protect themselves
   from their own side. The Army painted inverted "Vs" on
   allied tanks so colleagues would know not to shoot, and in
   some desert battles in Iraq, U.S. soldiers had to jump out
   of armored vehicles to wave red-lensed flashlights to
   signal fellow troops to stop shelling them.

   The soldiers shot by their side in Operation Desert Storm
   were victims of a technological mismatch. U.S. tanks were
   outfitted with the latest heat-locating sights that allowed
   them to detect enemy tanks at much longer distances than
   ever before, even at night, and to fire at them while
   moving. But the tank gunners, under pressure to decide
   whether to fire within seconds of spotting a target, lacked
   technological help in discerning through a screen of dust
   and smoke whether a shadowy blip on their scope was
   friendly or unfriendly.

   One machine developed since then -- a strobe light-like
   device for foot soldiers that emits signals detectable only
   by other U.S. troops wearing special goggles -- is being
   used by some units in Bosnia, and is available for units
   elsewhere. Another device, now being tested in Army
   laboratories, transmits laser beams to allow soldiers to
   identify themselves. But these contraptions do not address
   the problem of friendly fire between tanks, by far the more
   common form of such accidents in the Gulf War, officials
   said.

   Army officials are bracing for increased public interest in
   the issue owing to the July 12 release of the Twentieth
   Century Fox movie, "Courage Under Fire."

   The film stars Denzel Washington as a tank commander in the
   Iraqi war who is racked by guilt after he kills some of his
   troops in a tank battle.

   The new BCIS technology was built after the Army gave a
   contract to TRW Inc. of Cleveland in 1993 to develop it.

   Army officials say it has "met or exceeded all criteria" in
   tests.

   Several military officials, defense industry executives and
   independent experts said it could dramatically reduce
   fratricide among tanks, armored vehicles and helicopters.

   While agreeing BCIS is effective, Army officials want to
   subject it to new rounds of testing, a move some advocates
   see as an attempt to justify delaying BCIS.

   "The BCIS system works, and the Army is basically
   stalling," said David Rockwell, a senior analyst with the
   Teal Group, a northern Virginia defense consulting company,
   who has extensively studied so-called "combat
   identification" technologies. "The Army's not pushing
   it.... It boggles my mind why they wait for a disaster to
   happen."

   "It's a very successful program, and it protects soldiers
   against a real threat," Sa'adah said. He said he believes
   the Army practices "denial" on the subject of friendly
   fire. The Army denies the charge but acknowledge it stings.

   "Fratricide eats at the fiber of a military unit, and we
   take it very seriously," said Brig. Gen. John P. Rose,
   director of Army horizontal technology integration. "We've
   done a lot to address it. But we're somewhat defensive to
   critics who say we haven't." One of the briefing papers the
   Army distributes on the topic is headlined, "The Army is
   not ignoring combat I.D."

   Embedding BCIS on most Army tanks and armored vehicles
   would cost $180 million to $300 million. The BCIS machinery
   -- a set of antennas and transmitters -- costs about
   $15,000 per tank, plus up to $15,000 for installation.
   Advocates say that is cheap, considering the Abrams M-1A2
   tank, on which it would be installed, costs about $6.5
   million apiece.

   "To argue about $15,000 is absurd," said Sa'adah, who
   worked on the BCIS program and other anti-fratricide
   initiatives while in uniform. "It costs less than an
   average car."

   But the Army says it does not have the money to install
   BCIS, given what it asserts are tight budgets for weapons
   systems it feels it must acquire. "BCIS at present is
   unaffordable in terms of money available to the Army and
   because of competing demands," Rose said. Added Brig. Gen.
   John S. Caldwell, who helps run the service's efforts to
   "digitize" weaponry: "The Army's trying hard to keep BCIS
   alive."

   Army officials, stretching to rationalize their position on
   BCIS, say they have found ways other than technology to
   reduce fratricide, such as building a war machine so
   intimidating enemies will avoid taking it on. "Not getting
   in the battle is a way to cut down on fratricide," Caldwell
   said. "You convince the enemy they're in a losing game
   before they go into battle."

   Sa'adah echoes that point, asserting the key reason Army
   officials do not deploy BCIS is they doubt their tanks will
   be summoned for war anytime soon. "The Army's thinking is,
   'We'll keep BCIS on the shelf, and if we ever need it,
   we'll start manufacturing it.' " He says it is a
   justifiable stance, but a difficult one to enunciate
   publicly because the Army is spending grand amounts on the
   armored platforms on which BCIS would be installed -- $883
   million in 1996 alone to upgrade M-1A2 tanks and Bradley
   Fighting Vehicles with better communications, computers,
   armor and other features.

   In any case, the Army will test BCIS further in several
   maneuvers next year. The idea is less to see whether it
   works -- Army officials say it does. Rather, the new tests
   will examine, among other things, whether the Army can
   forgo BCIS and rely on another set of technologies to which
   the Army is heavily committed.

   BCIS's main competition tests is an ambitious array of
   technologies being installed on tanks and artillery --
   sensors, computers, high-tech screens and communications
   gear -- designed to give soldiers up-to-date intelligence
   on events unfolding in battle. The Army calls the
   multibillion-dollar program its "digitization" initiative.

   These digital technologies were not intended to prevent
   friendly fire, but now the Army is considering
   reconfiguring this collection of digital computers to
   handle this mission. While Army officials defend this plan
   as a prudent use of limited procurement funds, some
   Pentagon and industry fratricide experts say that is one
   assignment too many for the digitization network.

   Last year an Army review at White Sands Missile Range in
   New Mexico found the digitization plan is "not sufficient
   to prevent fratricide" without a combat identification
   system such as BCIS.

   A separate 1995 study by a Pentagon panel that studied
   fratricide concluded BCIS offers the "most payoff," and
   that digitization "contributes little in close battle,"
   when a tank gunner is deciding whether to fire at another
   tank, according to a memo prepared by the panel, the Combat
   Identification Architecture Working Group.

   One of BCIS's advantages is that a tank gunner learns
   whether another tank is friend or foe by looking down his
   gun sights at his target. But using the digitization gear,
   a gunner's eyes must jump back and forth between his sights
   and a complex map showing location of various combatants on
   the battlefield before deciding whether to fire.

   Moreover, while BCIS can answer "who goes there?" in well
   under a second, it can take a digital map up to 10 seconds
   to respond. That is a serious problem because tank gunners
   are under pressure to fire at an enemy tank before being
   fired on. "It's been shown time and again that in a tank
   battle, the guy who gets the first shot off in the first
   5-6 seconds is the winner," Rose said.

   The General Accounting Office, Congress's investigative
   arm, has backed delaying installation of Army
   anti-fratricide systems pending further studies on how to
   mesh them with the digitization plan, and with a separate
   Navy technology to end fratricide.

   It is anybody's guess what the tests will reveal, but Army
   officials say their budgets are not likely to loosen, even
   if BCIS emerges as the indispensable key to ending
   fratricide.

   "What if we can't afford it for everybody" in a unit, but
   only for some tanks? asked the Army's Caldwell. "What does
   that do for the confidence of soldiers who know not
   everybody has it? It's a complex question."

   A New Way to Tell Friend From foe

   Here is a description of the Battlefield Combat
   Indentification System (BCIS), designed by TRW, Inc.:

   Gulf War technology ...

   During the Gulf War, U.S crews used reflective tape or
   paint on their vehicles to identify themselves to
   colleagues. This system did not work well over the ranges
   of more than two miles common in modern tank battles.

   Since the Gulf War, the Army has affixed thermal panels on
   tanks. They are designed to register in thermal sighting
   devices as "cold" holes against the background of a "hot"
   target.

   ... and BCIS

   With BCIS, friendly targets are immediately identified
   through triple-checked microwave pulses. These encrypted
   signals change frequencies 43 times a second, making them
   resistant to jamming or detection by enemy forces.

   [Diagram of Tank 1 identifying Tank 2]

   [Steps of identification]

   1. Gunner in Tank 1 aligns weapon sight on Tank 2 and
   presses the laser range-finder button; this activates the
   BCIS signal.

   2. Tank 1 transmits encrypted queries to Tank 2 via its
   directional antenna.

   3. Tank 2's transponder receives the query through its
   omnidirectional antenna.

   4. Tank 2's transponder validates the query and responds to
   Tank 1. Tanks 2's crew is informed it has been
   interrogated.

   5. Gunner in Tank 1 sees a symbol in his gunsight
   indicating "friend" or "unknown." (See diagram below)

   [Diagram of data displayed in gunner's sight]
   
   Yellow circle: Friendly vehicle in sector.
   
   Readout of laser-designated distance to target. 

   One of these symbols will display: 
   
   Blinking red circle: Friendly vehicle in gunner's sight. 
   
   Solid red dot: Unknown vehicle.

   + Cost per unit: $15,000. The Army wants to reduce the cost
   to $10,800.

   + Probability of correct identification: 99 percent,
   according to TRW.

   + Range: 8.7 miles in clear weather 4.9 miles in rain.

   + Performance: Works in fog, rain, smoke, dust, foliage, at
   night.

   + Applications: Could be used on helicopters and individual
   soldiers.
