The Ogris fires detonite infused casings.
—In-Game Description
The Ogris is a Grineer rocket launcher unlockable through Chem Lab Research in the dojo. A slower projectile version of this is used by the Bombard, though the homing ability isn't present in the ClanTech version.
Silent (Enemies will not detect you when you blow their friends into pieces).
Can be fired while sprinting.
Ridiculously ammo efficient.
Moderately fast reload speed.
Effective at killing enemies behind cover.
Slow fire rate tends to make recoil irrelevant.
Disadvantages:
Deals FULL damage to the user if the rocket detonates too close (All damage will be dealt including elemental damage and effects (set on fire, etc.) making the Ogris very dangerous and ill-suited for close range combat.
Clumsy against large crowds of fast-moving enemies such as the Infested.
Has to be charged before it can fire.
One of the lowest rate of fire in the game.
Easy to jam trigger (see notes).
Blast damage is less efficient against armour.
Enemies can destroy the rockets with gunfire.
Slow projectile speed.
Optimal use relies heavily on proper positioning.
Enemy bodies will block AoE damage from hitting enemies behind.
