The biggest problem with Battle Drill is the words Battle and Drill.
When you call exactly the same thing an "Immediate Action Drill" or "Contact Drills" no one blinks. - and you can't train infantry without such things.
...and strangely, I note from chatting to my friends in the IDF, that the Israelis intuitively refer to training as "Drills." - which bearing in mind the British Army's part in forming the Palmach and thus the IDF may not be surprising.
