every country and every army in the world tells it's soldiers that sacrificing their lives for the sake of the war they are fighting is honorable and noble and that their families, friends, and nations are proud of them for doing so. how is that so much different than telling soldiers they will be rewarded in heaven for being martyrs? For those who are religious, if you sacrifice your life for the greater good (for the good side in a war between good and evil), isn't that a good deed? and don't good deeds get you into heaven?
