According to information from sources in the President's Office, Bankova is fundamentally against the mobilization of security forces, in particular police officers, to participate in combat operations at the front.
Andriy Yermak reportedly forbade the commander of the Ground Forces Oleksandr Syrsky to even raise the issue of the possible mobilization of security forces.
According to this information, it is important for the Office of the President to maintain the presence of bodyguards and law enforcement officers in the middle of the country. Policemen can act as substitutes for territorial procurement centers (TCC) in cities, which will allow maintaining order.
Earlier, Syrskyi proposed an alternative scenario to the Office of the President. According to his plan, 50% of military commissars and 50% of security forces should be sent to the front.
This decision raises some questions in the context of resources, since keeping a large part of the security forces in Ukraine may lead to the fact that there will be fewer people on the front to fight the aggressor, but in the OP it seems that stability on the home front is a priority.
