1. An electronic hand grenade comprising: a body having at least one charge therein;an electronic detonation unit attached to the body for detonating the at least one charge, and including an accelerometer, a controller containing an operating program for controlling operation of the electronic detonation unit and a detonator for providing a spark to ignite the at least one charge; anda pull pin removably attached to the electronic detonation unit, and configured to activate the electronic detonation unit upon removal thereof,wherein the accelerometer is configured to detect acceleration of the body in at least one of X, Y and Z directions, andthe operating program is configured to determine whether acceleration has been detected by the accelerometer and if an acceleration has been detected by the accelerometer, determine whether the acceleration detected by the accelerometer corresponds to throwing or rolling of the body, and if the acceleration detected by the accelerometer corresponds to throwing, determine whether the body has been subjected to an impact, and if the body is subjected to an impact, determine whether the body has traveled at least a minimum safe throwing distance, and if the body has traveled at least the minimum safe throwing distance, instruct the detonator to detonate the at least one charge; or if the acceleration detected by the accelerometer corresponds to rolling, determine whether the body has traveled at least a minimum safe rolling distance, and if the body has traveled at least the minimum safe rolling distance, instruct the detonator to detonate the at least one charge. 2. The electronic hand grenade of claim 1, wherein the electronic detonation unit further comprises a power source for powering the electronic detonation unit. 3. The electronic hand grenade of claim 1, wherein the detonator comprises a spark or bridgewire detonator. 4. The electronic hand grenade of claim 2, wherein the electronic detonation unit further comprises a switch connected between two opposing poles of the electronic detonation unit, the pull pin, when attached to the electronic detonation unit, preventing the switch from connecting together the two opposing poles, wherein removal of the pull pin permits the switch to connect the two opposing poles, thereby connecting the power source with the controller and the accelerometer. 5. The electronic hand grenade of claim 1, wherein the controller further comprises a counter for determining a time of flight of the body. 6. The electronic hand grenade of claim 5, wherein the controller is configured to calculate velocity, distance traveled and direction of travel of the body from the acceleration detected by the accelerometer and the time of flight of the body determined by the counter. 7. The electronic hand grenade of claim 1, wherein the hand grenade further comprises a time-activating button operatively connected to the controller, the button being depressible to activate a timer, the timer being set to a predetermined countdown time for detonating the at least one charge when the timer times out.
