===Stalker Squads===

Stalker squads specialise in reconnaissance and intelligence-gathering and were consummate masters of stealth, infiltration and sabotage deep behind enemy lines. 
Often remaining quiet when enemies were in sight, and reporting there location, direction, number, and armament to command so that other forces could be assigned to destroy them, allowing the Stalker squads to remain undetected, and continue providing up to date battlefield intelligence, as well as utilising their snipers and explosive charges to take out strategic and tactical objectives.

Stalker squads were also usually responsible for many of the guerrilla operations undertaken by the Children, using their skills of infiltration and sabotage to great effect behind enemy lines, working in conjunction with a Political Operations Officer to distribute propaganda, and win the local hearts and minds, while crushing the resolve and morale of their enemies with their constant hit-and-run attacks; always striking their target and disappearing before a retaliation could be organised.

The origins of the Stalker squads come from the Iron Rangers Heliwyr squads, who would use stealth and infiltration to get deep into enemy territory and help guide allied forces and harass enemy supply lines. 
Where other legions reconnaissance squads were used in a purely observational role, the Heliwyr and Stalker squads turned the humble scout into a fearsome formation, capable of wreaking great havoc.
The Iron Rangers often cooperated in operations with the Children early in their legions history, the two legions sharing an affinity for similar types of warfare, and thus the normally guarded Iron Rangers shared their experience and skills, the Children offering their own in return. 

These squads also spread to the other legions, although most were toned down from their incredibly clandestine beginnings, although still retaining the core concept of a guerrilla and reconnaissance role; it was from these formations that the later Adeptus Astartes Scout Marines were created after the Second Founding in the early 31st Millennium.
