Joining Nigerian army is like signing your own death warrant
May the soul of successful candidates please Rest in Peace in advance.
If Boko Haram doesn't get you, ISIS will. If you escape the deadly two you have Fulani bandits to contend with. Assuming you are still alive after 6 months, you have repentant terrorists in uniform serving with you that will not only slit your throat at the slightest opportunity but will give your patrol location away to their colleagues fighting you. So in all likelihood you will die in a Boko Haram ambush.
If in the unlikely event you managed to survive all of the above, you have grieving relatives of innocent citizens killed by the Nigerian soldiers waiting to kill you.
Only a complete fool will join the #Zoo army at this time. It's like signing your own death warrant. Nigerian Army is a terrorist organization in its own right therefore no sensible person will join them unless you are a terrorist yourself.
Shun them, save your life!
