It was rare for platoons to be supplied by the units for which they operated. However, this was not easily done, either by the battalions, who were faced with 'one more problem', or by the platoon leaders, who preferred to be supplied by their own squad for understandable reasons.
Conclusions.
After the experience of the invasion campaign, it seems that the autonomous C.K.M. squadron had no reason to exist as an independent unit for the following reasons:
1. Tactically, as a unit, it does not perform any mission, it only serves as a support weapon.
2. It does not appear in the overall battle and is never commanded in its entirety (except in a few situations of secondary importance).
3. It is used tactically at company level (platoons must perform the tasks of ordinary infantry units).
