Currently, in the Lyman area of Ukrainian , there are about 20,000 Russian troops stationed, and the Ukrainian army has formed a clamp-shaped encirclement of the area, which may cut off the Russian army's logistics and reinforcements supply lines at any time, and completely annihilate the Russian army in the Lyman area.
It is strange that, judging from the current situation, the Russian army is already in a passive situation in this area. But the Russian army did not retreat, and did not seem to plan to retreat. I don’t know if it’s for political face or if it’s a killer weapon behind it.
If there is no reserve means, it is best for the Russian army to withdraw from the area, because if there is no absolute advantage to rescue the Russian army surrounded by Lehman, the Russian army is already very passive in strategic direction, which is equivalent to the Ukrainian army holding a pawn and the initiative is in the hands of the Ukrainian army. Russia has a situation where he is passively beaten and led by the Ukrainian army. Withdrawal from the Russian army and looking for fighter jets should be a better choice for the Russian army at present.
For the Ukrainian army, from a strategic point of view, it may be more beneficial to Ukraine if there is no rush to eliminate the Russian army in Lehman. You can use the method of besieging the city to fight aid, and you can show weakness to the Russian army, encircle Leman's Russian army without annihilation, use them to lure the enemy, find fighter jets to eliminate the Russian army coming to aid, and consume Russia's vitality, because even if you eliminate Leman's more than 20,000 Russian troops, you will not be able to form a strategic victory situation. It should be more beneficial to use this favorable situation and expand your advantages.
Using Lehman to attract Russian troops to rescue, there is another favorable factor for Ukraine, which is to fight on the local level, which is home battle. For Ukraine, it is a war against aggression, which is conducive to the rise of morale. For the Russian army, this is a away battle, which is not conducive to boosting morale. So in this regard, it is more beneficial to Ukraine.
For Russia, unless it has an absolute advantage in firepower, it can use Leman to attract all Ukrainian troops to gather, and then use super weapons to wipe it out. If there is no such reserve method, Russia is better off withdrawing Leman as soon as possible and not take too much into consideration of political face, so that it may become passive and proactive.
