No, they do not. They use lager range finders giving them range within 
centimeters. Lager range finders are also man portable though bulky and
are 
used to call in accurate artillery fire and starlight devices give range

within a meter or two. If you've read "Rainbow Six" by Tom Clancy a tech

device currently available can triangulate and locate on video display
the 
electromagnetic field generated by a human heart it does NOT read 
chimpanzees, monkeys or gorillas either just humans with computer
displays 
utilizing IFF personnel devices geo postioning sattelites can pin point
and 
display all the friendlies in the area. Counter battery radars and
ladars can 
pinpoint artillery battery locations within milliseconds of the first
round 
revealing itself to the sensors. Not to allow range measurement in
sci-fi 
games borders on the silly.
