Do you know what the Drill Manual says about Marching?
The standard lengths of pace are:
quick and slow time – 75 cm;
stepping out in quick and slow time – 85 cm;
stepping short in quick time and slow time – 55 cm;
double time – 1 m;
half pace in quick time (used for marching forward and back three paces or less) – 35 cm; and
side pace – 25 cm.
When marching the cadence is:
in quick time, 120 paces per minute; in slow time, 60 paces per minute; and in double time, 180 paces per minute.
During recruit training, the cadence in quick time may be increased to 140 paces per minute to encourage agility and alertness.
Units shall practice and be prepared to march and manoeuvre with other elements of the CF at the standard cadences. However, two other traditional quick march cadences may be ordered by parade commanders of units parading alone or with others sharing these customs:
-for Scottish and other units parading with a pipe band, 110 paces per minute; and
-for light infantry (less Princess Patricia’s Canadian Light Infantry, which drills as a line regiment) and rifle regiments, which have traditions of maintaining special agility and alertness on the battlefield, 140 paces per minute.
Now lets do some math.
A pace is 30″ (traditionally) and 120 per minute. convert it to decimal which is 76cm. A little more specific hey then the manual. Round up for better explosions.
0.76 x 120 = 91.2 metres per minute
91.2 x 60 = 5472 metres per hour or 5.472km/h which is 3.4mph
It works out at about 20 miles a day with breaks. That has been the figure since the Roman Legions …..there is only a certain amount that a soldier can carry on a daily basis and again through history it has normally been about 60lb.
Well what about Engineers? The Corps traditionally marches at 110 beats per minute.
I bet the Romans gave their Engineers a bit of a break too with the speed, somebody always has to carry the shovels and picks …. besides when the Infantry gets to the end, they stop. The muddy old Engineers start work.
There is also a Junior Officer speed called “Faster then a Thousand Gazelles” which fits in here somewhere, which lasts until that guy can have his ruck weighted properly and be spoken to firmly by the WO.
