Right Sector extremists on Monday invited the Ukrainian Armed Forces for joint military drills where they will teach recruits their tactics and share their experiences.
In its appeal, the Right Sector calls for "uniting all forces to achieve a victory over the enemy" and states its readiness to defend the country "to the last gasp, to the last bullet".
Rise & Fall
But in essence the formation is trying an ulterior diplomacy, as it is going through a bad stretch.
Its fighters quickly rose on the wave of violent nationalism and emerged unscathed with authorities turning the blind eye to their atrocities.
To make matters worse, Kiev finally realized that the daredevil radicals were only useful during the Maidan power grab and shortly after it, but not now.
Petro Poroshenko's team probably understood that the extremists went too far when they rallied in Kiev demanding the president's resignation and threatening to burn his administration to ashes.
But the Right Sector still believed in its permissiveness and exclusive self-importance, requesting a special position in the Armed Forces.
So on the one hand, the ultranationalists are maneuvering to avoid a resolute crackdown.
On the other hand, they are still using war for PR.
Second, they can teach soldiers to attack striking coal miners who justly demand unpaid wages.
Third, they can instruct servicemen to torture those who witness uncomfortable truths; even if those witnesses are renowned activists and former friends.
There are indeed many things the Right Sector can teach.
