Destroyed building

A day, a week, a month, another month...
When will it end?! When will they leave you alone?!
Your house is destroyed, bullets are whistling. All that is left of the streets, friends and neighbors’ houses are ruins.
They are close by. On every corner, behind every wall, you hear muffled footsteps, the clang of the cartridge case, the clang of the bolt. You're like a live target.
Should you surrender or pull yourself together and shoot to kill?
A step... One more... A new clip... Recharge... A short burst...
Was it you or your opponent? Who made the final shot?
