Van de Berg was one of the men in the Dutch Resistance group along with De Leeuw, Goriss, Janssen, Smits and Van Dyke. They saved James Doyle after his B-17 Flying Fortress had been shot down over the Netherlands, their leader being Major Ingram (it is unclear whether Ingram was already a commanding officer of the SAS by the time of this mission). After Doyle joined their group, they continued their raid and succeeded in blowing up a train bridge, vital to the German war effort.
- The Dutch resistance men are among the few who can be seen wielding the Lee-Enfield in Call of Duty: United Offensive.
- If Smits is dead, Van de Berg will drive the escape lorry.
