Ukrainian Military Performance and Outlook

The Ukrainian Armed Forces (UAF) continue to face
disadvantages in seeking to defend Ukraine's territorial
integrity against Russian military forces. On the one hand,
since Russia's renewed invasion of Ukraine in February
2022, the UAF has successfully defended against, and in
some areas pushed back, Russian forces. On the other hand,
this resistance has come with losses in personnel and
equipment, and the overall outlook for the war remains
uncertain. The Biden Administration and Congress have
expressed support for Ukraine's defense of its territorial
integrity against Russia's invasion. An understanding of the
evolving state of the UAF may be of interest to Congress as
it continues to weigh policies potentially supporting
Ukraine's defense against Russian aggression.
Personnel
Some observers note that the UAF's initially positive
overall performance is due in part to the experience and
motivation of its personnel. The UAF has continued to
benefit from high levels of recruitment and motivation.
High losses, however, pose an ongoing challenge to the
UAF's ability to maintain effective and sustained
operations.
Since 2014, the UAF has gained important combat
experience fighting Russian-led forces in the Eastern
Ukraine regions of the Donbas, which has led to a large
proportion of trained, experienced veterans among
Ukraine's population. These veterans and other volunteers
(including foreign recruits, some with previous military
experience) were quickly mobilized into Ukraine's new,
volunteer Territorial Defense Forces (TDF) and Reserve,
without the need for lengthy training. Additionally, the high
level of experience and training among the recruits meant
they were able to operate artillery, tank, and support
systems that traditionally require time for reservists or
volunteers to master. These units were crucial in supporting
and enabling regular UAF units to spearhead resistance and
counteroffensives in multiple areas.
Since the beginning of the 2022 war, Ukraine reportedly
has suffered high levels of casualties. In early June 2022,
Ukrainian officials estimated losses of up to 100-200 killed
in action each day, but officials have not provided precise
figures. Losses are likely higher among regular UAF and
Special Forces units, forcing a greater reliance on TDF and
Reserve units. Due to losses and the need to rotate out
troops, Ukraine has had to recruit and train a substantial
amount of replacements. Unlike the initial period of war
when most recruits were veterans, most new recruits and
volunteers have little military experience. As a result, it
takes longer for the UAF to train new recruits.

The UAF also faces two major hurdles to training and
deploying new personnel. First, like many militaries,
Ukraine was in the process of developing a professional
noncommissioned officer (NCO) corps along NATO
standards before Russia's 2022 invasion. The UAF did not
have a fully developed professional NCO corps by the time
of the invasion and continued to deal with issues with
retention, professional development, and funding. As
described previously, the high proportion of trained
veterans, many with combat experience, mitigated to some
degree the need for an established NCO corps to train and
command new recruits. However, with mounting UAF
losses and recruits with no experience as replacements,
continuing the development of an effective NCO corps will
likely remain a major challenge and a key UAF priority.
Second, the UAF's need for immediate reinforcements
creates pressure to train new recruits to only the bare
minimum levels. Training recruits to conduct complex
operations and operate advanced weapon systems takes
longer, but both areas are widely considered necessary for
the UAF to sustain combat operations in the current
conflict.
Equipment
To date, the UAF also has sustained equipment losses.
Some UAF units appear to be operating without
mechanized or motorized vehicles support, likely due to
losses and maintenance issues. On June 15, Ukrainian
Brigadier General Volodymyr Karpenko estimated that
some UAF units sustained losses of up to 50% of their
equipment. Although this could be an overestimation, it
also likely reflects the UAF's need for further support
across tanks, armored personnel carriers, and artillery
systems.
Ukrainian officials have emphasized their need for long-
range rocket and artillery systems to counter Russia's
quantitative and qualitative advantage in long-range fire. At
the start of the war, Ukraine still relied on Soviet and
Russian 122mm and 152mm caliber rocket and artillery
systems. Ukraine also had a smaller number of longer-range
220mm and 300mm rocket systems, but it is unclear how
many are still in service.
The UAF relies primarily on Soviet-era and Russian
equipment. Russia has targeted Ukraine's large defense
industry with long-range missile strikes, affecting Ukraine's
ability to maintain, repair, and produce equipment and
ammunition to sustain operations. Ukraine's capacity to
repair and maintain equipment is likely degraded due to
Russian targeting, posing a hurdle to the UAF's ability to
sustain operations. Additionally, the Ukrainian defense
industry is likely unable to produce complex systems in
