TBS PHASE 3 REVISION EXAM QUESTIONS AND
SOLUTIONS MARKED A+
✔✔Fixed Fire - ✔✔Fire delivered on a point target. Little or no manipulation of the gun is
required to obtain and maintain effect on target.
✔✔Traversing Fire - ✔✔Fire delivered against a wide target requiring changes in
direction.
✔✔Searching Fire - ✔✔Fire delivered against a target in depth requiring changes in
elevation.
✔✔Traversing & Searching Fire - ✔✔Fire delivered against an oblique target requiring
changes in both elevation and direction
✔✔Swinging Traverse Fire - ✔✔Fire delivered against targets which require major
changes in direction with little or no change in elevation. Fired at the cyclic rate of fire
using the tripod.
✔✔Free Gun - ✔✔Fire delivered against moving targets that require major changes in
both direction and elevation. The T&E is not used as the manipulation is done by the
Gunner.
✔✔MG Employment Principles - ✔✔Pairs
Interlocking Fires
Coordination of Fire
Mutual Support
Defilade
Enfilade

Protection
✔✔MG Fighting Positions - ✔✔Primary

Horseshoe
Two-hole
✔✔General Support - ✔✔This is defined as "that support which is given to the
supported force as a whole and not to any particular subdivision thereof" according to
MCRP 5-2A.
, ✔✔Direct Support - ✔✔A unit in direct support of another unit is assigned the mission of
providing the support requested directly to the supported unit
✔✔Attachment - ✔✔The placement of a unit in an organization where such placement
is relatively temporary.
✔✔Classification of Offensive Fires - ✔✔Fires ISO
- Maneuver
- Isolation
- Assault
- Consolidation
✔✔Displacement Considerations - ✔✔Method

✔✔Final Protective Fires - ✔✔An immediately available, prearranged barrier of fire that
is designed to impede enemy movement across defensive lines or areas. Employed
only when close defensive fires have failed and can only be authorized by the
immediate commander or higher authority.
✔✔Principal Direction of Fire - ✔✔A predetermined line of machinegun fire that covers
the most dangerous avenue of approach to a defensive position with either plunging or
grazing fire, when possible, to produce front enfilade fire. The Principal Direction of Fire
will always be set on zero on the traversing bar, regardless of sector of fire.
✔✔Final Protective Line - ✔✔A predetermined line of grazing fire designed to stop an
enemy assault. It is fired across the frontage of a defensive line and is optimally as
close and as parallel to the defensive lines as possible, usually producing flanking
enfilade grazing fire.
