Principles of War

 Mass

Mass is to actually attempt to hurt the enemy rather than to just irritate or cause them a minor disconvenience. You basically hit them with a lot of force instead of just a little bit.

 Economy of Force

Economy of Force is the distribution of forces. You basically plan things out and wait for the perfect opportunity to strike rather than just going at them blindly.

Maneuver 

Maneuver is to find a way to put the enemy in a bad spot using different skills (agility of thought, plans, operations,and organizations.)

 Unity of Command

For every objective, seek unity of command and
unity of effort.

Security
Never permit the enemy to acquire unexpected advantage.

Security gives us the freedom to take action and not be as vulnerable to suprise or hostile acts.

 Suprise

Strike the enemy at a time or place or in a manner
for which he is unprepared

Suprise is literally what it sounds like. We gain an advantage by taking the enemy by suprise.

 Simplicity

Prepare clear, uncomplicated plans and concise
orders to ensure thorough understanding.

Basically keeping the plans simple to make sure that every one knows what they are doing.

 Objective

Direct every military operation toward a clearly
defined, decisive, and attainable objective.

Objective is to make sure everyone knows what the are supposed to be doing and how to do it.

 Offensive
Seize, retain, and exploit the initiative.

Offensive action is the most effective of all other actions to obtain a common objective. It is when a military force takes and holds the goal while making sure freedom is maintained.
