...from the rules....

"Depending on the value of the Vehicle Breakdown Parameter Data, it is possible that a unit consisting of vehicles will lose strength as it moves. The probability of this happening depends not only on the parameter data value, but also the quality of the unit and the movement cost associated with the move. However, a unit with a single vehicle is never eliminated by this process.

Given a movement cost of C for a given unit with V vehicles, a parameter data Breakdown value of B, and a quality modifier of Q, the probability that the movement will result in a strength loss of 1 vehicle is given by:

Probability = V * C * B / (40000 * Q)

Note that this probability is scaled so that when B = 1, then a 100 vehicle unit of C Quality will on average suffer a 1 vehicle loss when moving 100 hexes via primary road. The Quality Modifier is given by:

A Quality => Modifier = 1.2
B Quality => Modifier = 1.1
C Quality => Modifier = 1
D Quality => Modifier = 0.8
E Quality => Modifier = 0.6
F Quality => Modifier = 0.4

When a unit is flagged as being Low Reliability in the Order of Battle, then the probability of having a breakdown is 3 times the normal probability."

So value B is set for all vehicles of a particular side by the PDT, then quality and low reliability come into play.
