Because the grouping of the rocket bursts are not very tight, so its not advised to fire while moving.

While the ammo capacity of the MOD-3 looks generous for a rocket launcher, it is limited to fire at three round burst, 15 rockets are translated to only five bursts.

The missile's spread makes it ineffective for direct impacts past short range if the target is moving, due to its spiraling trajectory. A burst can inflict significant damage on even the most powerful enemies if all of the missiles make contact. The most ammo found in one spot in the game is when the Sergeant faces against a REV8 Leviathan in the Armacham Bio-Research Facility. The MOD-3 is also found in Perseus Mandate, though it is not as plentiful as it is in Extraction Point. Due to plentiful ammo, there will hardly be a shortage when facing powerful enemies. The MOD-3 is much more common in Extraction Point than in the first game, and is often found right before fighting a Power Armor.

The MOD-3 Rocket Launcher is quite rare, being found in only three places in the game twice in the enviroment and once held by a Heavy Armor in the Auburn District. First Encounter Assault Reconīoth Timelines F.E.A.R.
