Commandeering is derived from the word 'commandeer', which comes from the French 'commander' (meaning to order or command). The prefix 'com-' (meaning together) and 'mandare' (meaning to order) combine to convey the act of ordering something for one's use, often in a military context.
Think of 'ordering' ('commander') something 'together' ('com-') — that's why commandeer means to take control or order something for use.
