American Dictionary of the English Language

EQUIP', verb transitive

1. Properly, to dress; to habit. Hence, to furnish with arms, or a complete suit of arms, for military service. Thus we say, to equip men or troops for war; to equip a body of infantry or cavalry. But the word seems to include not only arms, but clothing, baggage, utensils, tents, and all the apparatus of an army, particularly when applied to a body of troops. Hence, to furnish with arms and warlike apparatus; as, to equip a regiment.

2. To furnish with men, artillery and munitions of war, as a ship. Hence, in common language, to fit for sea; to furnish with whatever is necessary for a voyage.
