In conventional wars military has to be prepared to fight short, intense and high tempo wars (e.g. 6 day war, Yom Kippur war, ODS....). In unconventional wars military has to be prepared to fight long, drawn out wars where most of the time there is little action overall.
While you cannot change gear in the manner of minutes, I believe that those who understand low-intensity conflicts have the ability to quickly make the shift to high-intensity operations than vice-versa.

Since "down on the line" the majority of the force is becoming trained in low intensity operation, the burden will be on the schoolhouse (BNCOC, ANCOC, OBC, CCC, CGSC, SAMS...) to be the main proponent for teaching high intensity tactics and doctrine. That is not the say the schoolhouse should not be teaching low-intensity conflict; they need to be teaching both.

In general, the strength of the Army lies in having leaders with the ability to learn and adapt quickly.
