About DERUYTER Training Support (DTS)
DTS is a nonprofit initiative from Walter Pennekamp, Piet Kruithof and Derk Wisman. It is organized and operated to benefit former marines needing extra mental, medical or financial attention. A secondary goal is to develop and maintain relationships between former Dutch marines and the Dutch Marine Corps. The main activity of DERUYTER is secondment of retired but current and physically fit marine corps specialists to operational units to support instruction, training and exercising. Secondment is executed under the flag of MSS DEFENCE guaranteeing management and back office support. MSS DEFENCE holds all licenses and insurances to execute the activity.

DTS is not operated by volunteers. There is professional staff. Salary expenses are carefully balanced against expenses to beneficiaries. DTS operates as a fiscally responsible business and is making a profit as it has to remain a fiscally viable entity. DTS has the responsibility of focusing on being professional, financially responsible, replacing self-interest and profit motive with mission motive. Any revenues that exceed expenses will be committed to the organization’s purpose. DERUYTER TRAINING SUPPORT is accountable to the Dutch Marine Corps and the seconded marine corps specialists.
