Military Land: Ukrainian Winter is Coming

As winter approaches Ukraine, it is an appropriate time to look at weather and its effects on the battlefield on both Ukrainian and Russian forces.

A military Intelligence Officer is primarily concerned with three things: Enemy, weather, and terrain.  Average winter temperatures in Ukraine range from -7°С to +2°C and according to the U.S. Army, this fits the definition of a “Wet Cold.” The main problem with the ‘wet-cold’ environment is that the ground becomes slushy and muddy; it is never fully frozen or dry. The issue is well known, so much so that both nations have a name for it: Ukrainians call it “bezdorizhzhia,” or roadlessness, and Russians, “rasputitsa,” or disagreeable travel. Winter’s effects on army operations are numerous.  These range from changes in operations, logistics, and personnel considerations.

Operations

First and foremost, the onset of winter considerably slows down army operations; especially on the offense. Defensive positions are advantageous because of the ability to maintain warmth and protection, compared to attacking in cold weather.

Military vehicles in this environment face particular mobility challenges, wheeled vehicles may require tire chains. Diesel engines start less well in cold and may require pre-heating or idling during cold periods already drawing on diminished Russian fuel supplies.  Tracked vehicles can swap out pads for cleats. However, while cleats can gain additional traction on ice and snow, they are of little use in the mud.

The freeze/thaw nature of the Ukrainian winter restricts avenues of approach mostly to roads, making it difficult for offensive ops. Roads are typically avoided as canalized ground (the restriction of movement to a narrow area because of terrain) makes it easy for artillery and anti-tank assets to defend against. This is more of an issue in the Southern area of operations where the ground is at a lower elevation and has higher water tables.

The ways to combat this challenge is to reorganize. Attacking forces can’t deploy on wide fronts. The Ukrainian army needs to break down into smaller formations (combat teams) with lighter guns/mortars in close support. Good communications with fire support assets is essential. Tanks and IFVs restricted to roads or higher firmer ground can provide direct fire support for infantry on the advance.  Soggy terrain also makes it harder for artillery to employ ‘shoot and scoot’ tactics making guns and launchers more vulnerable; especially in the defense.

Snow, ice, and cold temperatures affect munitions and military vehicles. Weapons and vehicles require special lubricants to operate at low temperatures. Other effects include sluggish performance of lubricants, leading to increased failure rate of engines. Batteries also suffer from reduced operating life.

Snow, ice, frozen ground, and low temperatures affect mine-laying operations. Burying mines in a frost layer may be difficult, requiring mines to be placed on top of the ground and then camouflaged. Snow or ice may prevent detonation, owing to freezing the firing device or isolating from pressure above.

Likewise, cold weather effects small arms operations.  Trigger and safety mechanisms may freeze if subject to condensation. Belt fed guns can jam if the ammunition has ice on it. Ironically, weapons need to be left outside to prevent freezing. Icing may prevent more complex weapons from operating including restraining launch systems or binding other moving parts. Some electrical parts may be susceptible to condensation and shorting.  System electronics also take considerably more time to warm up.

The weather does not only affect land ops. Due to the temperatures fluctuating around zero, there will likely be a reduction in Close Air Support missions and UAV sorties, for both reconnaissance and attack.  Fluctuating weather reduces flying hours, as visibility is hampered by fog and snow; the days are also shorter.

Battery operated drones will have reduced range, and engine operated drones will be harder to start and communicate with. Condensation may freeze and effect UAV sensors and video displays. Ice may accumulate on propellers and wings causing flight issues.

Personnel:

An army marches on its stomach, and a good warm bed doesn’t hurt either.

Due to the frequent freeze thaw cycles, clothing and equipment becomes perpetually wet and damp. Cold and dampness can put soldiers at risk of trench foot, hypothermia, and in extreme cases, frostbite. Handling of weapons becomes more difficult as the fingers and hands can freeze on metal parts in extreme cold. Gloves can prevent this, but make weapons handling clumsy.

Proper winter clothing is required to maintain body heat and to avoid such cold injuries. While Russians are no strangers to cold weather, it is highly unlikely that the recently mobilized have any access to cold weather gear. This will make for a very miserable existence, negatively effecting morale. Meanwhile NATO has committed to providing the Ukrainians with cold weather clothing.

Finally, rapid removal of the wounded from the battlefield is essential to their survival in all weather. However, cold weather makes it harder to reach, treat, and evacuate the wounded.  Inability to save wounded soldiers will also have a negative effect on morale.  Russia is already having problems with casualty evacuation, and it will only get worse as winter approaches.

Conclusion:

For Ukrainian and Russian military planners, the clock is ticking.  Already, rainy fall weather is bringing muddy conditions that are starting to limit the mobility of tanks and other heavy equipment.

The Ukrainian Army needs to continue to advance before bad weather sets in and consolidate their territorial gains. The UA needs to continue attacking supply lines and personnel concentration areas as attacking encampments, convoys, and supply depots deprives the enemy of food, shelter, and warmth. This operational pause will enable the UA to further shape the battlefield and attrit Russian forces before the resumption of offensive ops.

The cold weather will adversely impact Russian morale more so than the Ukrainian soldier.  The average Russian soldier is poorly-equipped, ill-supplied, and is hard-pressed to muster any rationale to put up with the miserable winter conditions. Despite the long history of Russian winter warfare, there is little evidence to suggest they are prepared for this Ukrainian winter.
