Before setting out the driver had keyed the tentscoordinates into a Navstar receiver so itcould guide him back again. No one knows exactly how many Navstar receivers ended up serving coalition forces along the Persian Gulf because mothers and fathers-and sweethearts too-located a few stray units on the shelves of marinesupply houses/plunked down their money and express mailed them to their loved ones in the Persian Gulf. A few resourceful soldiers called stateside suppliers long distance then used their credit cards to order receivers many of which arrived in Saudi Arabiaa dayortwolateraboardcommercialjetliners. Bythe timetheground war finally started 4000 to 7000 Navstar receivers were clutched in the hands of grateful American soldiers. They were used to guide fuel-starved airplanes for linkups with aerial tankers to pull in air strikes against enemy emplacements to guide mess trucks toward hungry troops and to vector Special Forcesunits intheir muffled dune buggies deep behindenemylines.

They then used their hand-held Navstar receivers to record the precise coordinates of each spring thus insuring fresh water supplies for onrushing troops.
