'combat-ready' originates from the combination of 'combat,' which comes from the Latin word 'combattere,' meaning 'to fight,' and 'ready,' from Old English 'ræde,' meaning 'prepared.'

'combat' evolved from the Latin 'combattere' through Old French 'combatre,' and 'ready' from Old English 'ræde,' eventually forming the modern English term 'combat-ready.'

Initially, 'combat' meant 'to fight,' and 'ready' meant 'prepared.' The combined term 'combat-ready' has retained its original meaning of being prepared for battle.
