Pls I Need your Advice On My Career Choice

Pls Honorable Nairalanders i'm a student and i have a burning desire to join any of the 'forces' upon graduation. I was unable to secure an admission into the prestigious NDA and i don't think i'll want to go for four more years after my graduation. This has left me with other options like Police, SSS. Pls I would like your candid opinions on the forces in view and possible facts on benefits (both cash & any other). Thanks.
