Order Militant

Your Monestary Order was created to protect something, knowledge like the Shaolin, perhaps Travelers like Knights Hospitaller. What ever your order was created to protect you are expected to do much with very little, you are expected to commit yourself to the cause beyond the regular bounds of promises, your entire being is committed to the Way set out by your Founding.
When first creating an Order Militant Monk you should choose or roll on the following table and pick two foundational tenants, if you ever break one of these you must do significant penance, if you break both without doing penance then you are ejected from the Order and may not advance any further within it's teachings.
Every two levels gain an additional Vow.

1.   I will give the one I am protecting any wealth or comfort that does not compromise my ability to continue to protect them.
2.   I will not allow the one I protect to become dependent on me any further than they were when we met.
3.   I will never betray my protected ones Secrets or confidence.
4.   I will never teach the skills I learn from my Temple until I am given permission.
5.   I own nothing, I use only things given to me and I will let them go without avarice or jealousy.
6.   I will never become intoxicated willingly or by laxity.
7.   I will never Lie deliberately.
8.   I will not willingly pro create.
9.   I will obey my teachers.
10. I will not rest (short or long) until I have practiced my kata's
11. I give no promises to anyone other than my Temple.
12. I will follow no Gods

Arsenal

When you choose this tradition at 3rd level, your special martial arts training leads you to master the use of certain weapons. 

Militant Order Weapons. Choose two types of weapons to be your Militant Order weapons: one Pole Arm weapon and one Ranged weapon.  You gain proficiency with these weapons if you don’t already have it. 

Agile Parry. If you make an unarmed strike as part of the Attack action on your turn and are holding a Militant Order weapon, you can use it to defend yourself if it is a melee weapon. You gain a +2 bonus to AC until the start of your next turn, while the weapon is in your hand and you aren’t incapacitated.
Militant Order Shot. You can use a bonus action on your turn to make your ranged attacks with a Militant Order weapon more deadly. When you do so, any target you hit with a ranged attack using a Militant Order weapon takes an extra 1d4 damage of the weapon’s type. You retain this benefit until the end of the current turn.

Defensive Bracers

In place of a Shield you have super thick or strong bracers, they count as a +2 Shield but this does not impart Shield proficiency, instead you are well trained at putting your bracers between you and danger, if you lose your Defensive Bracers, the abilities accrued are non functional until you get them back.
At level 7 these bracers are now a Magic Item for the purpose of destructive resistance.
As time goes on, this defense moves from being purely physical rejection of damage to magical rejection of damage, this you can activate with Ki Points

Sharpen the Self
It's not enough to defend, you need to know when the danger is coming. So you devise and learn a number of strategies to cope with understanding your environment.
You may take the following actions once per Long Rest.

Parapet: If you have 5 mins or more you may take objects in your immediate area and use them to create a fortified position, all attacks coming at your group while you remain in your fortified position are at disadvantage.

Body Guard: Designating a character as your protected individual, you may interpose yourself between all dangers and use your Reaction to defend them as if they were you for one Turn, you may extend this to additional turns for 1 Ki Point per turn within the same Combat Scene. You must take a long rest before using this feature again.

Sharpen the Senses: You quieten yourself and for 1 Ki point you may engage all of your senses to gather information, make a roll for seeing, smelling, hearing, temperature and vibration. Roll 1 D20 5 times, add the scores together and divide by 5 for your average, and add your Intelligence or Wisdom modifier.
