The following shows the minimum ratio of assemblers/machines and items required to produce chemical science packs such that all number of assemblers/machines are whole numbers. Items per min is calculated using [[assembling machine 3]] with no [[module]]s or [[beacon]]s and all assemblers running at full speed. The crafting of some intermediate products are not shown (due to the assumption that these items are available in large quantities within the factory). This table was produced using normal recipe difficulty.

The '''Military science pack''' is one of the four early game [[science pack]]s, the other three being the [[automation science pack]], the [[logistic science pack]], and the [[chemical science pack]].
It is used for [[research]] that allows the player to advance their military strength through the entire game, unlocking more bullet choices, gun choices, turrets, etc. It is the only type of science pack that is optional, in that it is not required to launch a rocket.

The following shows the minimum ratio of assemblers/machines and items required to produce military science pack such that all number of assemblers/machines are whole numbers. Items per min is calculated using [[assembling machine 3]] with no [[module]]s or [[beacon]]s and all assemblers running at full speed. The crafting of some intermediate products are not shown (due to the assumption that these items are available in large quantities within the factory).
