Former Ukrainian officer explains:

The tragedy after the enemy strike in the village of Myla caused a new surge of populism - those guilty of negligence should be shot and crucified. Therefore, my friends, I will write you an unpleasant truth. Since I am no longer officially a military serviceman or a civil servant, I can afford a little hate and swearing and the truth for my civilian friends.
Briefly, the main theses: everyone will fight, the role of the conditionally “civilian” population will be to mask military production, the military in general and their actions and military depots.
That is, a human shield, this is one of our, and mine included, missions in this war. Therefore, we should not whine, but be proud. I am sorry that I upset you, my civilian friends, and now in more detail.
The war devours a huge amount of ammunition, trains, they need to be produced, stored, and transported. If someone thinks that we have a huge number of warehouses in our country that meet all security requirements, are located in forests, and even belong to elves who will give them to you for free, then you are mistaken. Anyone who has ever placed a production facility knows what an ass it is, and this needs to be changed, the sooner the fewer victims there will be.
We want the Patriot to protect us, so that the bastards can shoot down the Shahed who are flying towards us, but we don’t want the missiles from that Patriot to be stored next to us, we don’t want the SAM itself to be standing near our house, we will write a bunch of complaints that an enemy agent will see somewhere and expose the position or warehouse. It won’t happen. Resign.
A little about camouflage:
military production outside the settlement, in the middle of the field it is impossible to camouflage, workers go there, cars go there, this time, no one will allocate SAM to cover a separate warehouse in the field. For this reason, almost everything, the life of the troops, military production, decentralized warehouses, it is better to hide among civilian life, which has been done for a long time, and will be done, and will be strengthened, because otherwise it is a defeat.
A little about efficiency: a city is a city not because people like to live in concrete cells, but because the city as a whole is a large factory with a large range of goods and services, and also at the intersection of logistical routes, and also a concentration of various specialists. By placing production in the city, it becomes more efficient. During war, efficiency is more important for us than security, so production must be in cities and use their infrastructure.
THERE IS NO CIVIL POPULATION
A modern war is a war of peoples, there are no civilians there. The Geneva Convention is not that it is outdated, it has never been effective. The Ottawa Convention, and other “peace-loving” conventions that are only followed by those who want peace, and those who want to wage aggressive wars simply use these conventions to disarm their victims.
You can’t set a border where there is military and where there is not - this is a soldier, and this one makes him a machine gun, and this one takes the one who makes the machine gun in the minibus, and this one feeds the one in the minibus … this one simply pays taxes. Everyone is involved in the life of the state and everyone is involved in the war.
Attacks on civilian infrastructure are unfortunately a common way of waging war.
Here is a quote from the wiki for you:
“The Commander of the Royal Air Force Bomber Corps, Arthur Harris, believed that the destruction of German workers, their families and their homes was as effective as the destruction of the industrial enterprises where these workers were employed. On May 27, 1943, Arthur Harris signed Bomber Command Order No. 173 on the operation codenamed “Gomorrah””
Our opponent also believes so, so do not flatter yourself with illusions.
What really needs to be done.
Do not whine and do not blame your own for Russian strikes, this is part of the enemy’s plan, so that the populists are forced to take military life into the field, where it is easy to destroy.
Facilitate all military needs - rent premises, to the military and for military production, at least tell where what is and who does what. Just as the military covers civilians at the border, civilians must cover and assist the military throughout the country.
We must recognize and accept that the life of, for example, a Patriot SAM crew is more valuable to the country than yours and mine, because next time this crew can save someone else. The life of a evader can generally become at least somewhat valuable only after the start of the BZVP.

i am not very smart. So be patient with this question, and answer patiently.

are they going to run out of people? Russia and Ukraine?
