Commandos: Behind Enemy Lines Beginner Tips - Stealth, Roles, and Objectives

Commandos: Behind Enemy Lines is a World War II real-time tactics game developed by Pyro Studios. The original Windows release was published by Eidos Interactive, while current digital storefronts may list Kalypso Media Digital or bundle it with other Commandos releases.

Content note: ESRB rates Commandos: Behind Enemy Lines T for Teen with Animated Blood and Animated Violence. This guide keeps war-combat discussion non-graphic and focused on player decisions.

This is a beginner guide for base Commandos: Behind Enemy Lines fundamentals: observing patrols, reading briefings, keeping every commando alive, using specialist tools, saving cleanly, and avoiding expansion or remaster confusion. It is not a full 20-mission walkthrough, compatibility guide, multiplayer setup guide, speedrun route, password list, or guide for Beyond the Call of Duty, Commandos 2/3 HD Remaster, or Commandos: Origins.

Essential Tips

1. Read the Briefing Before Touching the Squad

Every mission is a puzzle built around objectives, terrain, and the available team.

Start by checking the briefing, map notebook, objective reminder, enemy placement, and extraction logic before you move anyone. A route that works with the Marine, Sapper, and Driver may fail when the mission gives you a different squad.

2. Treat Every Commando as Irreplaceable

One dead specialist can end the mission, even if the objective looks almost complete.

Commandos is not a disposable-squad tactics game. Keep everyone alive, keep injured commandos away from unnecessary exposure, and avoid plans that gamble a specialist just to save a few seconds.

3. Observe Patrols Before Building a Plan

The first tool is information, not a knife, pistol, or grenade.

Watch enemy paths, pauses, sight cones, and overlapping patrols. If a guard is watched by another guard, solve the watcher first or create a timing window. The safest move is often waiting one more patrol cycle.

4. Use Crouch and Crawl Deliberately

Standing, running, and crawling change what enemies can see and hear.

Move slowly when the route is exposed. Crawl through risky outer vision when the terrain allows it, but remember that crawling is slow and bad positioning can still trap you.

5. Save After Stable Progress

Quicksaves are powerful only when the position is actually recoverable.

Use quicksave after clearing a guard cluster, reaching a safe hiding place, placing a key specialist, or completing a risky objective step. Do not save while spotted, surrounded, or seconds away from an alarm unless you are intentionally preserving a test state.

6. Keep Guns as Emergency Tools

Noise solves one problem and can create three more.

Pistols and gunfire can draw attention, start investigations, or trigger alarms. Use silent tools, timing, decoys, disguises, bodies, buildings, and patrol manipulation before turning a stealth route into a firefight.

7. Spend Limited Tools Like Mission Resources

Sniper rounds, explosives, boats, and special items are not generic ammo piles.

Check what the mission gives you and what the objective probably requires. Do not waste sniper rounds on easy close targets, throw explosives before confirming the target, or strand the Marine’s boat where the squad cannot use it later.

8. Match the Job to the Specialist

Wrong-man solutions are a common way to get stuck.

Use the Marine for water movement, the Driver for land vehicles, the Sapper for explosives and wire work, the Sniper for precise long-range removals, the Spy for disguise and distraction, and the Green Beret for close stealth work and decoy setups.

9. Control Bodies, Footprints, and Noise

Enemies react to more than visible commandos.

A body in a patrol path, gunfire near a barracks, an explosion, or tracks through snow or sand can pull guards out of position or cause alarms. Use those reactions only when the plan accounts for who will investigate and where your commandos will hide.

10. Finish the Objective With the Exit in Mind

Completing the target is not always the end of the mission flow.

Before you plant the bomb, free the prisoner, kill the target, or trigger a final action, make sure the squad can still regroup, board the right vehicle, and leave if the mission asks for extraction.

11. Expect High Difficulty Even With Beginner Advice

This is an old, strict tactics game, not a forgiving tutorial sandbox.

GOG describes the tactical gameplay as extremely challenging, and the manual frames missions as increasing in difficulty. A beginner guide can reduce avoidable mistakes, but it does not make blind routes reliable.

12. Keep Version Scope Tight

Do not mix base-game advice with add-on, remaster, or prequel mechanics.

The GOG Ammo Pack includes Beyond the Call of Duty, and the wider Commandos series has later remasters and newer entries. Use this guide for base Commandos: Behind Enemy Lines only unless a source or screenshot confirms the exact version you are playing.

Commando Roles

Commando	Beginner Role	Watch For
Green Beret	Close stealth, decoy setups, body and object handling	Needs safe timing and body control after silent takedowns
Driver	Land vehicles and vehicle-based mission tools	Other commandos may enter vehicles, but the Driver is the land-vehicle operator
Marine	Boats, diving, harpoon use, and water routes	Boat placement and pickup can matter later in the mission
Sapper	Explosives, grenades, mantraps, and pliers	Many explosive tools are limited or mission-dependent
Sniper	Long-range precision kills	Rifle ammunition is limited, so choose targets carefully
Spy	Uniform disguise, distraction, poison, and body handling	Suspicious actions can break disguise safety

Stealth and Objective Flow

Situation	First Habit	Why It Helps
New mission starts	Read briefing and scan the whole map	Objectives, danger points, and roster shape the solution
Guard cone blocks a route	Watch one full patrol cycle	Patrol timing is often safer than improvising
A body will be seen	Move it or use the reaction deliberately	Body discovery can trigger investigation or alarm pressure
A loud tool seems tempting	Ask what will hear it	Gunfire and explosions can pull extra enemies
A specialist has limited gear	Save it for objective-critical targets	Wasted explosives or sniper rounds can force restarts
A vehicle appears	Confirm who can operate it	The Driver handles land vehicles; the Marine handles water vehicles
A prisoner appears	Clear a safe path before opening the cell	Prisoners and rescued allies add routing risk
Objective is complete	Regroup before the final exit step	A scattered squad can fail late even after the target is done

Controls and Compatibility Caveats

Area	Guidance	Player Check
Objective reminder	Original manual lists Ctrl+B for current objectives	Current Steam/GOG behavior and keyboard layout
Saving	Original manual lists Ctrl+S quicksave and Ctrl+L quickload	Wrapper behavior and save/load bugs on modern systems
Stance	Original manual lists C to crawl and S to stand	Current keymap and any remapping support
Selection	Original manual uses portraits and number keys	Modern keyboard layouts and UI scaling
Take object	Original manual/GameFAQs use the hand action and H	Item-specific pickup quirks in each mission
Compatibility	Steam’s 2016 update addressed Windows 10 and several old bugs	Windows 11, Steam Deck/Proton, widescreen, high refresh, and community fixes
Multiplayer	Steam/manual describe co-op and LAN/TCP-IP structures	Current internet play, LAN setup, server tools, and security expectations

Common Mistakes to Avoid

1. Do not move before reading the briefing - The objective, roster, danger points, and escape route can change the whole plan.

2. Do not let one commando die for a shortcut - A single casualty can invalidate the mission.

3. Do not solve routine patrols with pistol fire - Noise can turn a controllable guard puzzle into an alarm problem.

4. Do not spend sniper rounds on targets another tool can handle - The Sniper is strongest when saved for targets that are hard to reach safely.

5. Do not plant explosives before checking the exit - A completed sabotage objective can still leave the squad in a bad position.

6. Do not leave bodies in watched routes - Visible bodies can pull guards, start investigations, or raise alarms.

7. Do not ignore footprints on snow or sand - Enemy reactions to tracks can disrupt a clean route.

8. Do not send the wrong specialist to a vehicle or mission item - Some tools only work for the commando trained to use them.

9. Do not free a prisoner into an uncleared path - Rescue objectives add movement risk after the door opens.

10. Do not split the squad so far that no one can support the objective - Late mission actions often need specialists staged near the right place.
