Is it permissible for a soldier whose work conditions do not allow him to fast to break his fast in Ramadan?

It is not permissible for you to break your fast in Ramadan while you are obligated to fast, unless you are traveling or ill with an illness that prevents you from fasting, as Allah Almighty says: ﴿And whoever is ill or on a journey - then an equal number of other days﴾, and as Allah Almighty says: ﴿And He has not placed upon you in religion any difficulty﴾, and ﴿Allah does not charge a soul except [with that within] its capacity﴾, and as the Prophet, peace and blessings be upon him, said: "When I command you to do something, do as much of it as you can."
