This works…

team "Nic Barth" station

team "Bruce Mutton" dog

instrument station "Nics Garmin Etrex GPS"

If ‘station’ is replaced with ‘instruments’, it also works fine.

However this crashes on the first line…

team "Nic Barth" position

team "Bruce Mutton" dog

instrument position "Nics Garmin Etrex GPS"

with the error

D:\Program Files\Therion\therion.exe: error -- ArthurNorthAreaINDEX.th [674] -- unknown team role – position

Therion Book p18 suggests it should work OK
