Command Push: With this technique you have your routes of advance firmed up and the role of reconnaissance is to clear the routes of hostile forces or gather information for the follow on forces to use as they advance down these predetermined avenues of advance.
This type of reconnaissance is faster, but could be fraught with danger if many of the routes are well defended and the you are forced by losses to stop regroup, replan, or doggedly continue pushing into the teeth of a well deployed enemy force (this last is often the answer for most players in CM). On the other hand, if done correctly this type of reconnaissance could be very effective if you have done a good and thorough terrain analysis, identified the key terrain and most likely enemy deployment zones. Then the speed of advance could be shocking and overwhelming for an opponent.
The German term Befehlstaktik, is similar to Command Push as it also uses previously determined orders and plan.
