IDF Rotates Key Military Brigades in Gaza Following October 2025 Ceasefire

IDF Completes Strategic Brigade Rotation in Gaza

The Israel Defense Forces (IDF) announced a significant rotation of military units in the Gaza Strip in late December 2025, a strategic move undertaken as part of ongoing operations following the October 2025 ceasefire agreement. Two brigades, the 2nd Reserve Infantry Brigade and the Kfir Brigade, were withdrawn from the territory and replaced by fresh units.

The rotation comes amidst continued efforts to secure areas under Israeli control and in anticipation of a possible new phase of the ceasefire, expected to commence in early 2026.

Outgoing Brigades' Achievements Highlighted

The 2nd Reserve Infantry Brigade, which operated under the command of the 252nd Division in northern Gaza, concluded its mission around December 18, 2025. According to IDF statements, the brigade successfully dismantled Hamas infrastructure, eliminated 'dozens of terrorists,' and destroyed numerous weapons caches, including explosive devices, mortars, shells, mines, rocket launchers, and rockets. A key achievement was securing the 'Yellow Line,' a demarcation that separates IDF-controlled areas from those still under Hamas influence.

Shortly after, around December 20, 2025, the Kfir Brigade was rotated out after two months of operations along the Yellow Line in southern Gaza. This infantry brigade, in cooperation with the Yahalom combat engineering unit, located and dismantled hundreds of terrorist infrastructure sites. Notable discoveries included an underground tunnel route approximately two kilometers long and another tunnel extending hundreds of meters beneath the Khan Yunis area. The Kfir Brigade also reported eliminating approximately 20 armed operatives during its deployment.

New Units and Ceasefire Context

The departing brigades have been replaced by the 16th Brigade, which took over from the 2nd Reserve Infantry Brigade, and the 188th Armored Brigade, which assumed responsibilities from the Kfir Brigade. It is noted that the Kfir and 188th Brigades are composed of soldiers undertaking mandatory military service, while the 2nd and 16th Brigades are reserve units.

The broader context for these rotations is the October 10, 2025, ceasefire agreement between Israel and Hamas. This agreement outlined a framework for a phased withdrawal of IDF forces contingent on Hamas returning hostages and disarming. The ceasefire also included provisions for the entry of humanitarian aid into Gaza, though reports indicate that the stipulated levels of aid have not consistently been met, contributing to an ongoing humanitarian crisis.

The 'Yellow Line' established by the ceasefire agreement runs for most of Gaza's length, with the IDF maintaining a presence along this line, which IDF Chief of Staff Lieutenant General Eyal Zamir has referred to as Israel's 'new border' with Gaza, controlling approximately 53 percent of the territory. Despite the ceasefire, both sides have reported numerous violations since its implementation.
