Hope its ok this way , I noticed a lot of people praing , I dont know eny budhist or shinto prayers but I know one of the 7 gods of luck in Japan , Bishamonten , he was a patron of wariors in the past mostly in modern Japan he is a patron of police, soldiers and rescue units , try to pray to him in your own way so he can bless them with luck - I hope its not wrong or disrispectfull to do it like this. sweatdrop
