interesting point, i have heard before that there was complaint from the brigades that they would get broken up and sent to separate fronts. I had assumed that the idea may be that high command does not trust brigade commander/staff enough to give them autonomy. in terms of brigade having to answer to multiple chains, it is not uncommon in war or any large organization for that matter, but i wonder how bad is it for Ukrainian forces? who do these commanders have to report to?
Instead of the Corps structure and the former Districts, Operational Commands (OC) were created - South, North, East, West. In 2016, the Reserve Corps was created, which remained the only Corps in the structure of the Armed Forces until last year. In 2014, the ATO headquarters was added, followed by the JFO. Already in 2016, the structure was broken again, as the Donetsk OTG [Operational-Tactical Group] appeared. In 2022, the OSGs [Operational-Strategic Groups] "Tavria" and "Khortytsia" were added to this structure. And several more OTGs appeared - Kharkiv, Odesa, Sumy, Lyman, Soledar, etc. Last year, the 9th and 10th Corps were created, as well as the 30th Marine Corps.
But OTGs/OSGs continue to exist in this mess, as do OCs. And this continues to generate ineffective management. After all, when you have a brigade commander - corps commander - OC commander - Ground Forces commander - commander-in-chief in a vertical command structure, decisions are made relatively quickly and efficiently. But when the OTG and OSG exist vertically next to the OC, and are even more important than the latter, this creates inefficiency. Because it is problematic to go through 2 more command channels in the hierarchy structure.
Some Ukrainian analysts call for the elimination of OTGs and OSGs in the future. This could only happen when the process of forming Corps is completed, and the OC command is reinforced by OTG/OSG commanders, forming fully functional OC HQs, where decisions are made quickly. At the same time, the strengthening of the OC staff should be from among officers who have proven themselves in combat and enjoy great respect among the military.
In short: a brigade commander may be required to report to both the OTG, OSG, OC and the Corps, which has created a real mess in Ukrainian C2.
In the current structure, OTGs are a Corps without having organic units attached to them. The problem is that OTGs have the responsibilities of a Corps, without having any units under them organically (i.e. permanently) and without consistency in terms of units under their command.
In any case, the Russian organization is much better organized and structured.
The Russian organization at the lower level is based on separate brigades and divisions (and no longer on BTGs as at the beginning of the invasion), with some of the former gradually being reformed into divisions as part of the reforms announced in 2023. They are subordinate to their respective CAA, which has jurisdiction in a specific sector (they are, in fact, Corps-sized formations). The top level is the Group of Forces (GoF), which acts like an Army Group (although it is the equivalent of a Field Army) and is the deployment of the Military Districts (MD) on the front. There is a lot of correspondence, coherence and unity between them - usually a GoF will include most of the units and formations of a MD, although it will often have units belonging to the same MD in other GoFs, as well as units under it that actually belong to other MDs. GoFs are usually led by the commander of the corresponding MD. At the central level, there is the Command of the Joint Group of Forces in the area “SMO” (chaired by Gerasimov). The distinction is clearly observable here.
Do you understand the mess?
