Lieutenant Colonel Norbert Archwood is Todd's former Commanding Officer in the United States army, a veteran of two wars and a licensed attorney. He comes to Todd's defense when Troy and Abed's investigation into the study group's sabotaged yam project for Biology 101 brings up Todd as the prime suspect. ("Basic Lupine Urology")
On their third year at Greendale, the study group's Biology 101 yam project was seemingly sabotaged. After some investigation by Troy and Abed they found that Star-Burns was an eye witness's to the crime. He put the blame on Todd Jacobson, a student who bore a grudge against the group due to an earlier bad encounter with them. Todd was brought to the Biology classroom before Professor Marshall Kane to answer for his crimes. Before he could defend himself, Lieutenant Colonel Norbert Archwood stepped in and stopped the proceedings. He announced himself as having been Todd's C.O. while he was in the army. He also stated his credentials as a lawyer and his intent on representing Todd as his attorney.
Archwood asked what the charges were against his client and the matter was brought before Dean Pelton in his office. Jeff, acting as the prosecuting attorney on behalf of the study group, stated that Star-Burns saw Todd flee the crime scene. Archwood challenged that their eye witness had no alibi himself for having been there and could be the guilty party. Pelton sided with Archwood and demanded Jeff reveal why Star-Burns was there. Jeff claimed their witness had immunity which angered Archwood who wondered why they would take a degenerates word over a decorated soldier like Todd. After Pelton threatened to fail the entire study group unless Jeff came clean about Star-Burns, Professor Kane stepped in.
He asserted his authority overruled Pelton claiming jurisdiction based on the fact the incident happened in his class. When he declared Star-Burns immunity to be upheld and the testimony entered into the record, Archwood strongly objected. Kane got face to face with Archwood and declared that he was laying down the law. He further added that he would preside over a hearing where both sides could present their cases to the classroom to let them decide. Archwood begrudgingly agreed and told Jeff he would see him in class before leaving. Sometime afterwards, Archwood got to Jeff's star witness and threatened Star-Burns that he would involve the real police in this matter. This caused serious damage to Jeff's case when Star-Burns went into hiding.
