Summary:
Green Stratagems are mainly focused on defense, area control, sentries, mines, and defensive emplacements. They can protect objectives, control enemy movement, and create safe zones for your squad. However, not every defensive Stratagem is equally useful. Here is a simple ranking based on damage, utility, cooldown, Helldivers 2 Items, and ease of use.
S Tier: Best Defensive Stratagems
Flame Sentry is one of the best all-around defensive options. It deals heavy fire damage, applies crowd control, spreads flames across the terrain, and works especially well in choke points. Its short cooldown also lets you deploy it frequently.
Anti-Tank Emplacement is another top-tier choice. It provides extremely high damage, excellent range, and enough firepower to destroy large enemies and objectives quickly. Its biggest weakness is slow turning speed, so it works best when you can maintain distance.
High A Tier: Strong and Reliable
HMG Emplacement combines heavy armor penetration with strong sustained damage. Unlike an automatic sentry, it requires manual control, but it is extremely effective when used from a good defensive position.
Shield Generator Relay provides unique protection against ranged attacks. It is particularly useful against factions that rely on projectiles and can help a coordinated squad hold an area safely.
Autocannon Sentry is excellent against patrols and groups of enemies. Its explosive rounds provide both strong direct damage and splash damage, although its slow turning speed makes placement important.
Gas Mortar Sentry offers useful long-range crowd control and area denial. Gas can damage heavily armored enemies while confusing them, making this a strong alternative to more traditional mortar options.
B Tier: Useful but Situational
Machine Gun Sentry is one of the easiest sentries to use. Its fast turning speed and short cooldown make it consistently useful on almost every mission.
Gatling Sentry deals damage faster but has a longer cooldown, so positioning matters more. It is powerful against large groups but can also become dangerous to teammates.
Incendiary Mines are excellent for defensive missions. Their fire damage and area denial make them especially effective at blocking enemy approaches.
Gas Mines, Anti-Tank Mines, Tesla Tower, Laser Sentry, and EMS Mortar Sentry all have strong niches. They can be very effective when their specific strengths match the mission, but they are less universally useful.
C Tier: Limited Options
Rocket Sentry suffers from slower projectiles and an upgrade issue, making the Autocannon Sentry a more attractive choice.
Standard Mortar Sentry can deal good area damage, but it becomes dangerous when enemies reach your team. It is better suited to missions where enemies can be kept at a distance.
Grenadier Emplacement provides strong explosive damage but has limited firing coverage, making it difficult to use effectively outside defensive positions.
Anti-Personnel Mines are simple and useful against smaller enemies, but their limited armor penetration and high team-killing potential make them less appealing than other minefields.
Final Thoughts
The best Green Stratagem depends on the mission and enemy faction. Flame Sentry and Anti-Tank Emplacement stand out for their overall power, while HMG Emplacement, Shield Generator Relay, cheap Helldivers 2 Items, and Autocannon Sentry offer strong defensive utility. Situational options such as mines, mortars, and Tesla Tower can still be excellent when used correctly. For higher difficulties, prioritize Stratagems that combine reliable damage with strong area control and safe positioning.
