Introduction to Command Tasks
Command tasks are a critical component of the Group Testing Officer (GTO) series during SSB selection. These practical exercises test a candidate's ability to apply mechanical principles, spatial reasoning, and resource management under time pressure.
💡 What This Guide Teaches
This guide focuses on the technical mechanics you need to solve command tasks successfully. Understanding physics principles like cantilever, leverage, and center of gravity will prevent you from failing due to ignorance of fundamentals.
⚠️ Important Disclaimer
Real SSB assessment is different: While this guide teaches the technical skills needed for command tasks, actual SSB GTO testing evaluates your Officer-Like Qualities (OLQs) through physical performance, team communication, and leadership behaviors on the ground. Mechanical knowledge is necessary but not sufficient for success.
By mastering the mechanics in this guide, you'll ensure that ignorance of physics won't be the reason you fail. You'll understand why certain solutions work, how to evaluate multiple approaches, and what constraints matter most.
Bridging Principles
Every command task involves creating a bridge, path, or crossing mechanism. Understanding the two fundamental bridging approaches is essential:
Simple Span
A plank or beam rests on two support points with the gap in between. Both ends are supported.
^^^GAP^^^
✅ When to use: Gap is shorter than plank length
Cantilever
A plank extends beyond its support point, using counterweight on one side to balance extension on the other.
^^^GAP^^^
✅ When to use: Gap exceeds plank length or support is limited
💡 Key Principle: Support Points
Every plank must have at least one stable support point. Without proper support, the plank will topple or collapse. Support can come from:
- Ground (safe zone)
- Another resource (previously placed plank or balli)
- Hook or anchor point
- Counterweight (for cantilever)
The Cantilever Principle
A cantilever is a rigid structural element that extends horizontally beyond its support point. This principle allows you to bridge gaps longer than your available resources.
How Cantilever Works
═══════════════╪═════╪═══════════════▶
[COUNTERWEIGHT] [GAP TO CROSS]
The pivot point acts as a fulcrum. The counterweight (anchor side) prevents the span side from tipping over. The longer the span extends, the more counterweight needed.
⚠️ Common Mistake
Insufficient counterweight: Many candidates place a plank with minimal anchor on one side and expect it to support weight on the extended span. Without proper counterweight or the 1/3 rule (explained next), the plank will tip into the gap.
✅ Pro Tip: Using Balli as Counterweight
If you have a heavy balli (15-20kg) available, place it on the anchor side of the plank to create a stable cantilever:
│
└─ Pivot: Rope + Hook
This allows you to extend much further than the 1/3 rule would normally permit.
The 1/3 Rule Explained
The 1/3 Rule is the most critical cantilever safety guideline: At least 1/3 of the plank length must be on the anchor (safe) side of the pivot point.
💡 The Formula
Anchor Length ≥ (1/3) × Total Plank Length
Or equivalently: Anchor Length ≥ (1/2) × Span Length
This ratio ensures the center of gravity remains over the support, preventing the plank from tipping.
Worked Example
Given:
- Plank length: 9 feet
- Gap to cross: 6 feet
Solution:
Required anchor = 9 ÷ 3 = 3 feet minimum
▲ ▲
Safe zone Over gap
✅ Result: Stable cantilever. The 3-foot anchor provides sufficient counterweight for the 6-foot span.
⚠️ What Happens If You Violate the 1/3 Rule?
If anchor length < 1/3 of plank length, the center of gravity shifts beyond the support point. The plank tips into the gap. In real SSB, this is a failed solution.

Insufficient anchor
Red Zone Constraints & Safety
In SSB command tasks, red zones represent out-of-bounds areas where you, your subordinates, and your resources cannot touch. These simulate dangerous terrain (water, mines, enemy territory).
⚠️ Critical Rule
Touching a red zone = Rule violation. In real SSB, GTOs immediately mark this as a planning failure. Your solution is invalidated even if it technically bridges the gap.
Why Red Zones Exist
- ✅ Test spatial awareness and precision
- ✅ Force candidates to plan carefully before execution
- ✅ Simulate real-world constraints (water, rough terrain)
- ✅ Reveal impulsive decision-making
What GTOs Observe
- 📋 Did you identify all red zones before starting?
- 📋 Did you visualize the full path beforehand?
- 📋 Did you adjust your plan when constraints appeared?
- 📋 How did you communicate hazards to subordinates?
✅ Strategic Planning for Red Zones
- Survey First: Before touching any resource, scan the entire canvas/ground for red zones
- Visualize Path: Mentally trace your bridge path. Where will each plank go?
- Margin of Safety: Plan placements with 6-12 inches clearance from red zones
- Subordinate Briefing: Tell subordinates explicitly: "Avoid the water/mines on the left"
- Re-check Before Placing: Verify clearance before committing each resource
Resource Management Strategy
You'll typically have limited resources: 2-4 planks of varying lengths, 1-2 ropes, 1-2 ballis, and 1-2 subordinates. Efficient resource management is key to success.
💡 The Inventory Analysis Method
Before attempting any solution, conduct a systematic inventory:
- List all resources: Note exact lengths and weights
- Measure the gap: Estimate distance to cross
- Calculate sufficiency: Can resources span the gap?
- Identify constraints: Heavy resources? Limited subordinates?
- Plan primary + backup: Have a Plan B if Plan A fails
Planks
Short planks (4-6 ft): Use for small gaps or as stepping stones
Long planks (8-12 ft): Primary bridge spans or cantilever extensions
Ropes
Purpose: Tie resources together, create anchor points, secure heavy loads
Tip: Use ropes to connect multiple short planks into one longer span
Ballis
Purpose: Counterweight for cantilever, stepping stone, vertical support
Tip: Heavy ballis (15-20kg) enable aggressive cantilevers
⚠️ Common Mistake: Overcomplicating
Candidates often use all available resources when fewer would suffice. Elegance matters.GTOs appreciate solutions that achieve the objective with minimal resource expenditure.
Example: If you can bridge a 6-foot gap with one 8-foot plank, don't waste time tying two 4-foot planks together.
Tactical Approaches by Puzzle Type
Command tasks typically follow 5 common templates. Recognizing the pattern helps you choose the right approach quickly.
🌊 River Crossing
Scenario: Start and finish platforms separated by a wide gap (water/ravine).
Key Decision: Is gap shorter or longer than your longest plank?
Gap ≤ Plank Length
✅ Simple span: Place plank across, ends supported on both sides
Gap > Plank Length
✅ Cantilever: Use counterweight (balli) and extend plank beyond normal reach
🧱 Wall Barrier
Scenario: Vertical wall between start and finish. Must climb over.
Approach: Create a ramp or ladder using planks.
Solution Pattern:
- Lean long plank against wall at 45-60° angle
- Secure base with balli or subordinate holding
- Test stability before climbing
- Use rope to tie plank to wall top if available
🏝️ Island Platform
Scenario: Start → Island → Finish. Two gaps to bridge.
Challenge: Island platform is narrow. Can't fit many resources.
Two-Stage Solution:
- Stage 1: Bridge Start → Island with first plank
- Transfer: Walk across, carry second plank to island
- Stage 2: Bridge Island → Finish with second plank
- Key: Ensure island platform is wide enough to support plank end
⛏️ Deep Trench
Scenario: Deep vertical drop between start and finish. Horizontal span needed.
Solution: Use vertical poles (ballis or short planks) as support in trench.
Three-Point Support:
- Place balli vertically in trench center as intermediate support
- Lay long plank: Start → Balli → Finish
- Secure plank to balli with rope if available
- Test load-bearing before crossing
🔄 Corner Challenge
Scenario: Path requires 90° turn. Start → Platform → Finish (L-shaped).
Challenge: Must bridge two perpendicular gaps in sequence.
Sequential Bridging:
- Leg 1: Bridge horizontal gap first (Start → Corner platform)
- Rotate: Turn 90° on corner platform
- Leg 2: Bridge vertical gap (Corner → Finish)
- Key: Corner platform must be large enough to stand and maneuver
Common Mistakes & How to Avoid Them
1. Placing Without Planning (Rushing)
The Mistake: Candidates immediately grab resources and start placing without surveying the full task.
Why It Fails: They discover red zones or constraints mid-execution, forcing them to backtrack and waste time.
✅ How to Fix:
Spend the first 30 seconds only observing: Identify start, finish, gaps, red zones, and resources. Then formulate a plan before touching anything.
2. Ignoring Red Zones (Spatial Awareness Failure)
The Mistake: Placing a plank that slightly touches or crosses a red zone boundary.
Why It Fails: Rule violation. GTOs mark this as lack of attention to detail.
✅ How to Fix:
Visualize before placing: Mentally trace where the resource will land. Check clearance from all red zones. Leave a safety margin.
3. Using Heavy Resources Unnecessarily
The Mistake: Attempting to carry and place a 40kg plank that requires 2 subordinates when a lighter 20kg plank would work.
Why It Fails: Wastes time and subordinate capacity. Shows poor resource optimization.
✅ How to Fix:
Always check weight requirements: Choose the lightest resource that still spans the gap. Save subordinates for tasks that truly need them.
4. Not Considering Cantilever Options
The Mistake: Giving up when the gap exceeds plank length, not realizing cantilever is possible.
Why It Fails: Candidate declares task "impossible" when a solution exists.
✅ How to Fix:
Ask: "Can I use cantilever?" If you have a counterweight (balli) or anchor point (hook, rope), you can extend beyond normal plank reach.
5. Poor Communication with Subordinates
The Mistake: Not briefing subordinates on the plan, red zones, or their specific roles.
Why It Fails: Subordinates make errors (touching red zones, dropping planks) because they weren't informed.
✅ How to Fix:
Brief clearly before executing:
- "We'll bridge this gap with the 8-foot plank"
- "Watch out for the red zone on the left - don't step there"
- "You hold this end, I'll secure the other end"
