Tactically, the use of gas weapons is to make territory unavailable to the enemy, typically for a short period of time.
In this role, chemical weapons are of limited effectiveness and debatable tactical worth. There are a few reasons for this:
Even in WW-I, which was a splendid example of static ground emplacements, checmical weapons were not very effective. Both sides had effective countermeasures, and varible weather conditions made these weapons a 1-edged sword. Also, phosgene, the most effective gas used in WW-I, accounting for 80% of the deaths attributed to gas, had roughly a 24 hour onset time, which means that it didn't do much at first, and this complicated planning.
it could take a while to activate the poison and its affects
Probably right when they started using poison gas because they already knew about poison gas from World War 2
To kill/maim the enemy, as is the purpose of most weapons of war.
The purpose of a gas meter is to monitor how much gas a particular house is using. Customers are then billed according to how much gas they have used from the meter.
Poison gas was never a decisive military weapon, since it is very unpredictable. A change in the direction of the wind can cause the gas that you were using to attack the enemy, to blow back in your direction and kill you instead. Nonetheless, poison gas is still feared, and armies continue to be equipped with gas masks, just in case.
The purpose of a heater is to heat up the room when it is cold; by using gas
Yes, using a gas monitor will lower your gas bill. The purpose of the monitor is to allow you to see how much you are using, and therefore, how much you can conserve.
