Our Team

AFG is founded by former military professionals with extensive experience within the military forces. The founders are still very much involved with the readiness of the military. Learn more about the history of AFG.


An international team in which Dutch, American, and English experts optimally prepare trainees to act effectively in war situations. The powerful combination of military and civilian experts provides the best learning experience for your people.

A careful selection process means that only the best qualified experts work at AFG. We put together an international training team to ensure the training program has the most relevant and up-to-date information. Our experts have had hands-on experience under the most challenging military conditions. We are eager to use this experience to help take you and your team to the next level.


AFG is in staat om in korte tijd meerdere instructieteams tegelijkertijd in te zetten bij grote klantvragen. Vaak bestaat 1 instructieteam uit 4 à 5 experts die zelfstandig trainingsprogramma’s kunnen aanbieden. Een projectleider staat altijd aan het hoofd van een training zodat de klant een aanspreekpunt heeft en de kwaliteit kan bewaken. 

Omdat wij werken met een grote flexibele schil zijn wij in staat om minimaal 8 instructieteams tegelijkertijd in te zetten. Dit vertaalt zich naar bijna 100 deelnemers per trainingscyclus.  

  Historie: Hart voor opleiden en trainen

July 2017: Geert van Oosterhout and Niels Hardam catch up during a network meeting of the Netherlands Maritime Special Operation Forces. They share experiences of the past turbulent years, including their missions to Afghanistan and Mali.

Geert and Niels have 30+ years of combined experience within the Marine Corps in leadership positions. After leaving the military, they both continue their career as entrepreneurs. The military has a special place in their hearts, they still feel very involved with the wellbeing of their former colleagues. Knowing the organisation from the inside out, and also seeing the developments in the world, they spot several opportunities for the military to develop their knowledge and skills in a faster and more efficient way.

Geert shares information about his recently started company Advanced Forces Group, with which he wants to support the Ministry of Defence with innovative education. Niels agrees with this direction, and both of them soon develop joint plans. They focus on the external educator-role for the Ministry of Defence. Increasing operational readiness, strengthening educational capacity and sustainably innovating the curriculum of the Ministry of Defence become their core objectives.

They verify this direction with various generals and other operational military commanders. The concept received a lot of enthusiasm and within a few months, the first courses had been successfully realized. Collaborations were set up with several other training institutes within the Ministry of Defence, and we look forward to continuing our AFG story.
