Tactical movement is the discipline by which a unit moves on terrain minimising the probability of being observed, engaged or tracked by artillery and drones. On the Ukrainian front, movement is the variable that separates a squad that arrives intact from one that takes losses during the approach alone. This chapter presents doctrinal principles — not offensive assault procedures.
Foundational principles
Four principles govern all light-infantry movement: dispersion, terrain use, mutual security, controlled tempo. FPV and ISR saturation make any visible concentration a target. Every metre moved must be covered deliberately.
- Dispersion: spacing between soldiers sufficient to prevent a single munition neutralising more than one
- Terrain use: exploit undulations, vegetation, shadow, buildings to break line of sight
- Mutual security: every element has someone watching while it moves
- Controlled tempo: alternation of movement, halt, observation — never continuous travel without listening
Basic formations
Formations are a visual language: they communicate to the commander where the risk sits and where the firepower sits. No formation is universally good; the choice depends on terrain, expected threat and mission.
| Formation | Typical use | Advantage | Limit |
|---|---|---|---|
| Column | Fast movement on trail or covered line | Speed, control, low frontal signature | Vulnerable to frontal fire and mines |
| File | Movement behind linear cover (wall, ditch) | Maximum lateral silhouette reduction | Vulnerable to enfilade fire |
| Wedge | Advance in open terrain | Fire in 3 sectors, wide reconnaissance | Larger footprint, visible signature |
| Line | Final approach or sweep | Maximum frontal firepower | Hard to control, maximum exposure |
| Diamond | 360° security, halts, rest | Full coverage, suited to halt | Slow in movement, footprint |
Formations shift fluidly: a squad goes from wedge to file to column within minutes depending on the cover available. Transitions must be silent and based on pre-agreed signals.
Dispersion and FPV threat
Spacing between soldiers, historically fixed at 3-5 metres for light infantry, has grown on the Ukrainian front. The logic is simple: an FPV with anti-personnel charge affects a few-metre radius; dispersion breaks the ability of a single munition to hit more than one.
- Minimum spacing in FPV threat zone: 8-15 metres between soldiers
- Greater spacing in open ground, reduced in dense cover
- Never concentrate during halts, information exchange, waiting
- Consider the vertical: a multi-storey building disperses in height too
- Rescue teams do not run together toward a casualty — they alternate
This chapter describes movement and dispersion principles. Assault procedures, trench-clearing or close-cover engagement procedures are out of scope for a reference manual: they must be learned in units with qualified instructors and rehearsed in live training.
Bounding overwatch — concept
Bounding overwatch is the principle by which one element moves while another observes, ready to provide suppressive fire. It is a doctrinal concept, not a rigid procedure: it applies at team level (two fire teams of a squad), squad level (two squads of a platoon), or single soldier in tight spaces.
- Element A moves to a pre-identified covered position
- Element B stays in observation position with weapons ready to cover A
- When A is in cover and has cleared the sector, A becomes overwatch
- B moves to the next position while A covers
- Bound length depends on threat: short under fire, longer in approach
The 'successive bounds' variant moves A beyond B; the 'alternate bounds' variant moves A up to B's line then B beyond A. Choice depends on cover availability and required tempo.
Reading the terrain
Terrain dictates movement. Before moving, the unit identifies lines of sight, lines of fire, lines of cover, obstacles, key points and likely threat directions. The OCOKA acronym (Observation, Cover and concealment, Obstacles, Key terrain, Avenues of approach) is a standard NATO mnemonic.
- Observation: from where the enemy can see us, from where we can see them
- Cover and concealment: cover (stops rounds) and concealment (hides from view)
- Obstacles: natural (rivers, cliffs) and artificial (mines, wire)
- Key terrain: points (high ground, junctions, bridges) whose possession confers advantage
- Avenues of approach: usable approach routes for us or the enemy
A bush conceals but does not stop a round. A brick wall stops rounds but not an FPV with anti-armour charge. Cover is threat-specific: always assess it against the expected weapon, not in the abstract.
Observation cycle
Movement alternates active and passive phases. The passive phase — halt, listen, observe — is where the unit reduces its signature and reads the environment. Skipping it for haste is one of the most common errors of untrained volunteers.
- Halt: stop in cover, not on the route
- Listen: 30-60 seconds of full listening, no talking, no movement
- Observe: visual sectorisation, each soldier watches an assigned arc
- Decide: the leader decides the next bound based on what was gathered
- Move: rapid movement to the next cover
Common mistakes
- Walking as a tight group because 'it feels safer'
- Cutting across open fields to save time
- Stopping on the route instead of in cover off to the side
- Continuing to move under open sky while knowing you are observed
- Constant predictable tempo that aids enemy targeting
- Relying on speed instead of cover
- Ignoring the vertical: buildings, trees, drones at altitude
- Talking during observation halts
Lessons learned Ukraine
On the Bakhmut, Avdiivka, Robotyne fronts, and today in the Kharkiv and Pokrovsk zones, dispersion has moved from theoretical norm to condition of survival. Squads moving as compact units are detected by persistent ISR within minutes and engaged by FPV or artillery within the first hour. Squads moving dispersed, briefly, between pre-identified covers, complete the move. Movement is not a run: it is a sequence of intelligent pauses between short bounds.
