Iran Update, December 19, 2023

December 19, 2023 - ISW Press

Israel has degraded Hamas’ North Gaza Brigade, which is consistent with CTP-ISW's observation that Israel appears to be nearing the final stages of its clearing operation in the northern Gaza Strip. The Israel Defense Forces (IDF) announced the beginning of clearing operations in Jabalia on November 18. The IDF reported on December 19 that it completely “dismantled” Hamas’ three battalions operating in Jabalia. About 500 suspected Palestinians fighters surrendered to Israeli forces in the Jabalia refugee camp, some of whom belong to Hamas and Palestinian Islamic Jihad (PIJ). Israeli Army Radio reported that the IDF fought “hard battles” in Jabalia against Palestinian militias for more than two weeks until Israeli forces had killed over 1,000 fighters. IDF Brigadier General Itzik Cohen said that the fighting in Jabalia "resulted in the dismantling of the military capacity” of Hamas’ North Gaza Brigade. The IDF estimated on December 19 that there are only a few militia fighters left in the Jabalia area.

Russian President Vladimir Putin is increasingly invoking the Kremlin's pre-invasion pseudo-historical rhetoric to cast himself as a modern Russian tsar and framing the invasion of Ukraine as a historically justified imperial reconquest. Putin addressed the Russian Ministry of Defense (MoD) Collegium on December 19 and largely reiterated boilerplate Kremlin rhetoric on the war in Ukraine by blaming NATO and the collective West for encroaching on Russia's borders and exculpated himself for issues faced by the Russian Armed Forces in Ukraine by deflecting the blame towards the Russian MoD bureaucracy. Putin additionally lauded Russian battlefield operations and Russia's defense industrial base’s net output in 2023, furthering several of his standard talking points. Putin once again invoked the concept of "compatriots abroad" when discussing residents in "southeastern Ukraine" who, he asserted, have historical, cultural, and linguistic attachments to Russia, in order to justify the invasion of Ukraine on ideological grounds.

Israel appears to be nearing the final stages of its clearing operation in the northern Gaza Strip. Israeli ground forces advanced into the northern Gaza Strip on October 27. Israeli clearing operations have relied on ground, air, and naval forces to destroy Hamas’ military infrastructure, namely its tunnel system and command structure. Palestinian militia fighters have clashed with Israeli forces in virtually all neighborhoods of the northern Gaza Strip since October 27. The Israeli Army Radio reported that the IDF has killed between 6,000 and 7,000 Palestinian militia fighters since the war began. Operations in the northern Gaza Strip likely resulted in most of the deaths. CTP-ISW defines “degrade” as a temporary effect whereby a unit’s losses seriously impede its ability to continue executing assigned missions while the unit remains able to operate.

A combination of artillery ammunition shortages and delays in the provision of Western security assistance is likely causing Ukrainian forces to husband materiel and may delay future Ukrainian counteroffensive operations. Ukrainian Tavriisk Group of Forces Commander Brigadier General Oleksandr Tarnavskyi stated in an interview with Reuters published on December 18 that Ukrainian forces have shortages of 122mm and 152mm shells along the entire frontline. Tarnavskyi stated that the shortages are prompting Ukrainian forces to redistribute artillery ammunition and replan military tasks. Ukrainian Deputy Defense Minister General Ivan Havrylyuk also acknowledged on December 18 that Ukrainian artillery ammunition shortages will continue. Tarnavskyi stated that Russian forces are also having issues with artillery ammunition, although Ukrainian and Western officials have reportedly assessed that the Russian forces are currently conducting artillery fire at a rate five to seven times greater than the Ukrainian forces.

Russian President Vladimir Putin threatened Finland and the wider NATO alliance in a statement ostensibly meant to dismiss concerns about the threat that Russia poses to NATO. Putin gave an extended interview with Russian state TV channel Rossiya 1 on December 17, wherein he attempted to deny US President Joe Biden’s December 6 warning that Russia would attack a NATO country in the future if it won the war in Ukraine. Putin argued that Russia does not have any geopolitical, economic, military, or territorial reason to fight NATO and that Russia is interested in developing relations with NATO member states. Putin followed this supposed reassurance with an accusation that NATO member states artificially created conflict between Russia and Finland and “dragged“ Finland into the NATO alliance. Putin stated that “there will be problems” with Finland and that Finland’s NATO accession prompted Russian officials to start forming the Leningrad Military District (LMD) and concentrating military units in northwestern Russia. The Russian military is currently redividing the Western Military District (WMD) to reform the LMD and the Moscow Military District (MMD) as part of a long-term restructuring and expansion effort that aims to prepare Russia for a potential future large-scale conventional war against NATO. The WMD is responsible for the Russian border with NATO members Lithuania, Latvia, Estonia, and Finland but has largely been committed to the fight in Ukraine, where it has incurred significant losses. The restoration of the LMD and MMD is likely intended to balance Russian operational requirements in Ukraine with Russian military posturing along the Russian border with NATO. Putin’s justification for the formation of the LMD, which will be responsible for an area bordering Finland, Sweden, and the Arctic, suggests that he sees the LMD as a military response to the “problems” of current and future NATO members in Scandinavia.

Israeli forces uncovered an advanced and extensive Hamas tunnel system in the northern Gaza Strip. The Israel Defense Forces (IDF) reported on December 17 that its forces had uncovered four kilometers of the tunnel near the Erez crossing in recent weeks. The tunnel is wide enough for vehicles to pass through it, reinforced with concrete, and connected to electricity and communications infrastructure. Israel said one section of the tunnel is the largest that it has discovered in the Gaza Strip and 400 meters from Israeli territory. The IDF stated that it was not familiar with the tunnel route nor its enormous scope prior to the war. The Wall Street Journal published a map of the tunnel system that Hamas has created below the Gaza Strip based on data from 2014, which includes a singular tunnel running south of the Erez checkpoint. The IDF published a map on December 17 of the entire tunnel network that it has uncovered, which shows a notable expansion of the tunnels’ coverage and complexity compared to the 2014 data.

Ukrainian Strikes Have Changed Russian Naval Operations in the Black Sea

December 16, 2023 - ISW Press

Key takeaway: Ukrainian strikes against Russian Black Sea Fleet (BSF) assets have changed Russian naval operating patterns, causing the BSF to move some ships away from its main base in occupied Sevastopol, Crimea and hampering the BSF’s ability to interfere with maritime trade in the western part of the Black Sea. Ukrainian strikes have likely caused the BSF to set conditions for a more permanent basing pattern along the eastern Black Sea coast as it transfers naval assets away from Crimea and expands a small port in de facto Russian-controlled Ochamchire, Abkhazia. Ukrainian strikes against BSF assets have successfully facilitated the use of Ukraine’s Black Sea grain corridor as international support for the corridor continues to increase despite Russia’s withdrawal from the Black Sea Grain Initiative and military threats against it.

The Houthis refocused their attack campaign to target Israel directly rather than international shipping and may have concluded that they achieved their objective of halting shipping through the Red Sea.

Ukrainian forces continue operations on the east (left) bank of the Dnipro River in Kherson Oblast amid reported difficult conditions in the area as part of an apparent effort to set conditions for future Ukrainian operations and the resettlement of west (right) bank Kherson Oblast. The New York Times published a series of interviews with Ukrainian military personnel operating on the east bank and along the Dnipro River on December 16, wherein the commander of a Ukrainian regiment stated that Ukrainian drone strikes have heavily suppressed Russian long-range artillery on the east bank in recent months. Ukrainian officials previously stated that Ukrainian forces established several bridgeheads on the east bank as part of an operation that aims to push Russian forces out of artillery range of west bank Kherson Oblast. The reported suppression of long-range Russian artillery may allow Ukrainian forces to operate more freely in near rear areas in west bank Kherson Oblast, which may partially explain intensified Russian glide bomb strikes against Ukrainian targets on the west bank.The much more abundant 152mm tube artillery systems that Russian forces widely operate in Ukraine have an approximate range of 25km, although Russian forces are unlikely to deploy these systems to immediate frontline areas due to the threat of Ukrainian counterbattery fire.

Iran and its so-called “Axis of Resistance” are exploiting the Israel-Hamas war to demonstrate their capability to control a key maritime route and chokepoint in the Middle East. The Houthis have conducted almost daily drone and missile attacks against commercial vessels transiting the Bab al Mandeb since December 9.
