noun
army
AR-mee/ˈɑːrmi/
A large organized military force that fights on land.
The army unit marches in a disciplined formation across the open ground.

Etymology
Armée named an armed troop or expedition, not specifically a land force. English army developed the sense of a trained, equipped military body and later became restricted to land warfare.
In context
Tens of thousands of men, most of them farmers and tradesmen with varying degrees of military training, assembled under county lieutenants to form the land army that would resist any Spanish force that actually made it ashore.
