Because they have to prevent the enemy from advancing; they don't have to destroy the enemy.
They're clearly unable to destroy the enemy.
Russia now will try to encircle as much of the Ukrainian army as possible, probably take Kiev, the pieces of land it's interested in and the conclude the war.
If the Ukrainian army were to let the Russians through, with small sabotage in mind they would get nothing in return.
By the time the sabotage becomes problematic, the rest of Ukraine will be taken already.
@rastinza Knowing who is your enemy would help with the prevention and ukrainians are capable of destruction
@kreyren
I don't understand what you mean: they know who their enemiy is. Ukrainians are clearly outnumbered and outgunned.
They weren't even able to retake the Donbas region from rebels, when the frontline was much smaller.
Attacking for them would mean a sure defeat, as they would weaken the defence line.
Letting the enemy through means there's no defense line anymore and they're acting from within enemy lines, where they would have no supplies and would quickly get mopped up.
This doesn't look like a war that will last long, thus setting up a resistance behind enemy lines would probably achieve nothing.
@rastinza The russians are using ukrainian uniforms captured from dead soliders.. It's probably difficult to identify them as they infiltrate kyiv
They weren't able to retake donbas with russian army on the border supporting the rebels
and resistence is critical now
@rastinza works in airsoft why wouldn't it work there? Enemy won't have enough of the time to adjust their disguise
