The Universal Granate

For this work I invented a small story that inspired me in the process.
A small story:

The universal grenade developed by i-tech corp has 3 modes of action between which can be switched using a fingerprint. There are such regimes:
The Standard Granate (STD)
Explosion by Timer (Time)
Mine (MINA) срабатывающий от пересечения лазерного луча направленный от гранаты
