Howdy!
Short and sweet. I suspect a problem and suggest the following:
The Traveller Book (201, 1982)
Page 38, WEAPONS USAGE, Square Grid Activity (Correction): Walking speed should be 17 squares per combat round (not 8 squares) and running speed should be 33 squares per combat round (not 16), to match the Speeds table on page 47, as well as other sources. Greater speeds are in multiples of 17 squares per combat round (not 8).
The size of the squares are 1.5 meters on page 38 and page 47 (Range Bands). These ranges are:
17 (1.5 meter) squares = 25.5 meters
33 (1.5 meter) squares = 49.5 meters
I've played Deluxe Traveller since it came out.
1 range band = 25 meters
Walking movement per combat round = 1 range band = 25 meters
Running movement per combat round = 2 range bands = 50 meters
Starter Taveller (page 20) states the same movement/range band rules as Deluxe Traveller.
In Striker, personnel move 50 meters per turn (30 seconds) while walking, 100 meters while running. Converted to Classic Traveller, personnel move 25 meters per turn (15 seconds) while walking, 50 meters while running.
Are the numbers given on page 38 correct, which are based upon Snapshot? I have only read the Snapshot rules and haven't looked deeply into the AP system.
A 12 meter (8 square) walking speed and a 24 meter (16 square) running speed doesn't seem to jive.
