Can fireworks be used in war?

basically, jews,buddhists,muslims pray head down to satan. during the night christian earthlybowdowns count 40 times more than daily earthlybowdowns. since, most of the time witches pray during the night against christians, it's best to pray at night ...maybe you could do 2000 christian earthlybowdowns.. notice that muslims-jews-buddhists stay head down which shows that they worship satan; christians have to get up super fast showing allegiance to Christ and not the devil. so, christian earthlybowdowns: u face east, legs together (so that demon don't run underneath ur legs); u look at the eyes of icon (energy goes ur way according to saint Pelageya of Ryazan); u make proper Orthodox sign of the cross (first three fingers together as if u had a pinch of salt in them; thumb always straight; ring and pinky to palm; firmly touch forehead: "in the name of the Father"; firmly touch 1cm above belly button: "and of the Son", raise hand to chest level and now move to right shoulder where there bones meet: "and of the Holy"; move to left shoulder: "Spirit. Amen"; release the fingers; hand down by ur side); u bow down on ur knees (knees together), then put hands together on the floor, then forehead on top of backofhands; as soon as ur forehead touches the back of hands, get up super fast showing allegiance to Christ (and not the devil). do 2000 times during the night against witches. 'cuz witches work hard for satan (by praying like three hours); you have to show them respect by outworking them; u feel me? but of course when u tired u could pray the Jesus prayer at least three times every hour (don't sleep 4 more than 1 hour; wake up and pray the Jesus prayer three times; then u can rest a little bit; in case witches pray real hard to satan, then u have to pray to Jesus as many times as possible); thank u; forgive me rudeness.

Industrial grade mortar fireworks certainly could be. There's usually a few fatalities relating to the improper use of these at displays every year. Some of the heavy duty stuff available to private citizens could leave a mark too. But they would be a desperation weapon, employed when you had absolutely no access to anything else, and, unless the enemy was at a similar disadvantage, it would be a very short, one sided war. Fireworks are extremely inaccurate, inefficient and ineffective compared to firearms

To celebrate victories, sure.

Yeh if you want your enemy to win
