No inspection ready squad ever passed combat. Five second grenade fuses burn down in three seconds. The enemy diversion you are ignoring is the main attack. Radios function perfectly until you need fire support. If you take more than your fair share of objectives, you will have more than your fair share to take.
Professional soldiers are predictable, but the world is full of amateurs.
Parade ground inspections are to combat readiness as messhall food is to cuisine. When in doubt empty the magazine. Snow is not neutral.
