got a deep appreciation for accuracy...We didn't want to do those more than once! Our required accuracy was 1:20,000, but with the T-2 Theodolite (mils) doing triangulation, we often got accuracy greater than 1:100,000. The 10tst Airborne told us once that with our field surveys, they could put an 8" artillery shell in your back pocket at 30Km (20 miles) on the first shot. Quite a complement (especially from the 10st).
In those days (1969), the closest thing we had to anything like GPS was the Azimuth Gyro. What an amazing instrument. Only used it three times, twice in Veit Nam, too sensitive for a combat zone.

Naturally, I asked him "if there is no chain and there is no throwing involved, why do you call it throwing a chain"? The reply was unpleasant at best, but I did learn how to do it quite well by the end of the day. …
