A/M-23 EMS Mortar Sentry

“

A turret firing static field generators that slow the advance of enemies.

— Ship Management Terminal

The A/M-23 EMS Mortar Sentry is a defensive stratagem. It is a mortar sentry reconfigured to fire EMS rounds capable to slowing and stunning enemies. It is especially effective when placed behind cover as it can disable enemies without the chance of it being destroyed.

Tactical Information

• This is a very effective sentry for supporting Helldivers and Sentries in an assault or defense, as it has no risk of friendly fire like other sentries
  • Compared to the A/M-12 Mortar Sentry, the EMS sentry only fires 1 shell at a time so despite it's lower total ammo supply, it has an even lower potential downtime provided all the necessary upgrades whilst firing continuously. It's minimum potential downtime is 30 seconds (96 seconds without upgrades).
  • If Helldivers do not try to avoid the stun, they might get killed by enemy attacks.
  • The shell of the EMS Mortar can be fatal if it lands directly atop a Helldiver.
• Compared to other stuns like the EMS strike or stun grenade, the mortar fires a lot more stuns. However, targeting is automatic, so it might not stun a high-priority target.
  • This can be offset with the Cross-Platform Compatibility upgrade which will cause the sentry to prioritize targets pinged by the owner.
• The mortar has a range of 125 meters
  • Pings specify the distance between the target and the camera
