The organization has declared its task to create a network of decentralized "resistance" cells on the territory of Europe, to build an ethnic Neo-Nazi community based on the ideology of primordialism.

The main structure of the organization consists of autonomous groups of neo-Nazis, local Skinhead movement natives and youth representatives dissatisfied with state policy.

Also, in the absence of specific tasks (set by higher departments in a structural hierarchical system), activities at the lower levels of the organization are not suspended, but are transferred to full autonomy of the group.

In the absence of these tasks, the participants of the Ethnic National Association at the autonomous level continue their agitation activities, social work and actions.

The organization actively uses all kinds of ways to spread and search for new participants for ideological "recruitment" into its ranks (its representatives are also looking for foreign contacts with European identitarianists).

[7] Since 15 April 2019, ENU has been holding a series of closed lectures of an extremist orientation, during which methods of combating law enforcement agencies are discussed, and the organization also announces recruitment to its ranks in the territory of the Russian Federation.

[citation needed] Since August 2019, the organization has been massively conducting propaganda raids on the territory of Russia, Ukraine and Belarus, using leaflets, stickers and graffiti.

The National Corps itself is confident that the perpetrators are political opponents from among those who previously "poured urine" on Yevgeny Strokan,[12] a like-minded person involved in the case of the attack on journalists "Shariy.net" by Vitaly Regor.

On 26 October 2020, ENU attempts to disrupt the Odesa local elections by leaving a dummy improvised explosive device in the building of the regional state administration.

[14][non-primary source needed] On 2 April 2021, an alleged participant of an Ethnic National Union was detained, who was preparing explosives for an action to intimidate the Muslim population in Altai.

Officially, the activities of an Ethnic National Association are not prohibited, the organization is not listed in the register as extremist or terrorist, but at the same time attempts are systematically made to capture its participants (during criminal prosecution for propaganda of fascism and extremism).
