Imperial Guard Fire Support Resource

FSR is fundamentally different to Vehicle Cap. FSR is determined by both the infrastructure (both structures & addons) and infantry alive on the battlefield. FSR is a regenerative resource (working similar to Ork pop) and a cap that accumulates similar to how Requisition or Power does, but has an upper limit.

In addition to being used for vehicles, it is also used for all Heavy Weapon Teams (which are available in Tier 1).

There are multiple stacking approaches to deploy more vehicles. The Imperial Guard do not make a harsh delineated decision between Infantry and Vehicles.
 * Deploying vast numbers of guardsmen.
 * This involves researching Squad Cap Researches,
 * Getting a 2nd HQ
 * Building more Infantry Commands.
 * Improve your vehicle production.
 * Build add-ons on your Mechanized Command, which provides both increased production speed % and more FSR.
 * Build more Mechanized Command(s).
 * Build the Mars Pattern, which can also have Add-Ons.
 * Each guardsmen (model, not squad) increases the FSR rate by +2. Each sarge by +4. Each commander by +5. Each minihero by +5.
 * FSR allows the Imperial Guard to have far more vehicles on the field than any other race.
 * The enemy will seek to slaughter your infantry forces, in order to prevent the oncoming onslaught of armoured divisions.
 * The enemy will seek to slaughter your infantry forces, in order to prevent the oncoming onslaught of armoured divisions.

IG FSR Pop Units Overview
20 FSR cost is roughly equivalent to 1 Vehicle Pop. *1 Recall that the Landspeeder and Rhino cost 1 pop, yet the Chimera costs 40 FSR. Mobile Infantry is more expensive for the Imperial Guard.

*2 Both Leman Russ variants (Battle Tank and Demolisher) have a shared total max of 3. Leman Russ Demolisher Tank also are max 1.

Racial Uniqueness

Unlike the other races, Imperial Guard:
 * Can build a range of mini-heroes (up to 2 of each) in Tier 1: Commissar, Priest and Psyker.
 * Each Infantry Command provides +2 Squad cap (enough for a guardsmen squad), thus increasing both your production and capacity.
 * Instead of Vehicle Population, Imperial Guard use Fire Support Resource (FSR).
 * Can spend their Vehicle Pop in Tier 1.5, through the use of Heavy Weapon Teams.

Squad Cap
With an initial population of 10 (including your first Infantry Command), this permits a combination of the following Tier 1/1.5 units: Guardsmen (2 pop), Kasrkin (3 pop):
 * 3 guardsmen (perhaps fast armoury or more mini-heroes)
 * 5 guardsmen
 * 2x Kasrkin + 3x guardsmen
 * 1x Kasrkin + 3x guardsmen (perhaps fast armoury or more mini-heroes)
