Raids (Lord+) - ::sendtroops (1,000,000 coins) spawns your boss and an escort squad. Order them:

• ::troops advance - they fight independently; you earn their kills.
• ::troops follow - they guard you.

Campaigns (Minister+) - ::campaign [city] marches a column to a hostile city (currently Varrock), breaks its garrison, and seizes loot. Every contributor splits the war-chest.

Conquest (King) - ::conquest [city] is the full-army version: larger forces, bigger payout.

You pay the cost up front, so coordinate with your company before launching.
