Romans 10:13-15

13 For whomsoever shall call upon the name of the Lord shall be saved.
14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
(Isaiah 52:7)

Infantry is the branch of an army that fights on foot. In the natural, the Infantry is the oldest branch of the military armed forces. Infantrymen are land-based soldiers and are specifically trained to engage the enemy face-to-face. Because of this role, in the natural, they historically suffer the greatest level of casualties in combat. Here, training for the Infantry will focus on the following:

1. Greater Emphasis on Discipline
2. Spiritual Strength & Fitness
   
3. Spontaneous Sustained Aggression

Although reduced in relative numbers, because of advancements in military technology, the Infantry still remains as the backbone of modern armies, and is today more lethal than ever before. In order for the Infantry to be effective, reliance is placed on organized formations in battle. These closely  knit formations allow officers to retain control and maintain discipline amongst the ranks.

The advantage that the Infantry has is its ability to access and maneuver in terrain that may be otherwise inaccessible. In order for the Infantry to operate successfully, there must be a common standardized guide to action. This common frame of reference for military operations is developed by linking the following:

1. Biblical Theory (Protestant Theology)
   
2. Historical Experience (Testimony)
   
3. Experimentation
4. Practice
5. Initiative and Creative Thinking

1. Attack
2. Defend
3. Patrol
4. Pursue
5. Escort
6. Maneuver
7. Surveillance
8. Reserve
9. Construction
10. Raid/Hostage Rescue
11. Urban Combat

Infantrymen must be vigilant at all times and closely monitor the positions of team-mates and leaders while being on the look out constantly for the enemy. This behaviour needs to be instinctive and simultaneous.
