Operational Role

In wartime 201 Engineer Combat Group would be tasked with keeping open tactically and logistically important roads in the Corps Rear Area. In addition, it was to prepare alternative crossings across the Weser and Aller rivers, for which 105 and 155 Pontoon Bridge Company would be kept in reserve.4

1.It should be noted that the designation Engineer Combat Group is somewhat delusive: this formation type and its subordinate units were neither  designed nor equipped for combat engineering; see for instance VS 5-154, I-1. In 1975 the more adequate designation Geniegroep was reverted to the previously used Geniegevechtsgroep, apparently because it was an (internally) well established designation and the new one caused confusion.

5.RIM was the Dutch acronym for Direct Influx into Mobilisable Units (Rechtstreekse Instroming in Mobilisabele Eenheden). GRIM was a variant of this system, meaning "Largely RIM" (Grotendeels Rechtstreekse Instroming in Mobilisabele Eenheden).
