Who is ‘He’

With josh always high and morale that can never die;
Has an iron fist for treason, but a velvet glove for innocents every season;
All night he stays awake putting his life at stake;
Be it an earthquake or a boulder, he never gives a cold shoulder;
He comes with different names, but protecting people is only what he aims;
With his family he doesn’t stand, for defending his motherland is the cardinal task at hand;
He might either return home walkin’ or inside a coffin, but always returns with a smilin’ grin!
He remains undeterred by the lies a cabal peddles, as in the abode of truth he nestles;
But… who is ‘he’?
‘He’ is a soldier made of mettle and for compromises with the nation, he won’t settle!
