Interesting tank crew and points discovery...

[Der Kuenstler]

Here's one response to my same post at Battlefront about it:

"The crew members don't exist as a separate unit until the vehicle is abandoned, at which point the program spawns an infantry unit - the crew - if it determines any crew survived the vehicle's destruction.

Each unit is worth points, so indeed a crew can score you points in addition to the points for the vehicle.

There are specific cases in which this doesn't make sense, but in general it's a good system."
