It is unlikely that scriptures will allow the concept of a "warrior Sannyasi" because dealing with weapons is mentioned as one of the reasons that brings about a Sannyasi's downfall.
A full meal given by one person, pride, envy, adorning with perfume
and flowers, betel leaves, injunction, amusement, desire for pleasure,
elixir, boasting, reviling, imparting blessings, astrology, buying and
selling, rites, ritual disputes, violating the commands of the
teacher, involvement in quarrels and reconciliations, vehicles,
couches, white clothes, masturbation, sleeping during the day, metal
begging bowls, poison, weapons, seeds, injuring, fierceness, sexual
intercourse, observances, such as those of a householder, which were
abandoned through renunciation, all social divisions such as
lineage,father's and mother's families, and wealth—these are
forbidden. He who resorts to them will sink downward.
Immovable and movable property, seeds, metal objects, poison, and
weapons: these six an ascetic shall refrain from accepting, as he
would urine and excrement.
Outside a time of distress, an ascetic shall never carry any
provisions for a journey. During a time of distress when food is
unavailable, he may take with him a cooked dish.
Brihat Sannyasa Upanishad
From here you can read the Upanishad I am quoting from. Translation is slightly different here and I'm giving it below.
A wise man, though very old, shall not trust in women though very old. Even in very old patched garments old cloth will stick (when
stitched).
Immovable property, mobile things (servants), seed (for cultivation), gold, gum-myrrh and weapon these six an ascetic shall
not take up as (though they were)
urine and faeces.
Verses are from Adhyaya two of the text.
