Knowledge (Military)

Identify Military Groups (DC 30-Fame)
This skill can be used to identify via insignia, symbol, or trademark a military or para-military organization. The DC is 30, but it is decreased based on the fame of the organization. For example, the Coalition is an incredibly well-known military organization, and has a fame rating of 20. So, the DC to identify the Coalition is only 10.

Tactical Bonuses (DC 15)
When fighting in a unit of more than five people, or when fighting using large groups, a player can use K. (Military) to provide a tactical bonus to their troops. Succeeding on this DC gives a +1 to all attack, damage, and saving throw rolls, as well as 1 temporary hit-point per hit-die. This number increases by 1 for every 10 that the DC is exceeded, to a maximum of +5 with a roll of 55. This bonus lasts until the group is forced to rest.

Foreign Country
When in a country that they are unfamiliar with (have not put at least 1 point into knowledge Local while in said country), they have a -15 to all Knowledge (Military) checks involving groups native to that country.

Action
Identifying a military group is usually a swift action unless under extenuating circumstances, and providing Tactical bonuses usually requires a half-hour per ten people to be inspired.
