Is there a restriction on movement after coming in as reinforcements? assume i have eleventy bajillion CP to use these stratagems.

Cult ambushing a large unit of bikers onto the battlefield.

Use of Lying in Wait, Followed by A perfect Ambush + Extra Explosives + Drive by Demolitions ( all in the movement Phase)

Can Move the biker unit within this instance of APA? in the Shooting phase I use Extra Explosives + Drive by demolitions again, can I then move again? Charging is restricted. but is the movement from Drive by demotions? Stratagems below so you don't have to look them up.

LYING IN WAIT
Genestealer Cults Stratagem
Revealing themselves from carefully prepared positions, the true believers appear as if from thin air.
Use this Stratagem when you set up a unit from your army as reinforcements that has the Cult Ambush ability and that was set up underground. When setting up that unit, it can be set up anywhere on the battlefield that is more than 3" from any enemy models, but that unit cannot make a charge move this turn.

A PERFECT AMBUSH
Genestealer Cults Stratagem
The faithful spring the perfect ambush; the foe is greeted with a hail of bullets and a horde of fanatics bearing down upon them.
Use this Stratagem in the Movement phase, immediately after you set up an INFANTRY or BIKER unit from your army that has the Cult Ambush ability on the battlefield. That unit can either move D6" (even if it has arrived as reinforcements), or it can shoot with all of its ranged weapons as if it were your Shooting phase (using this Stratagem in your own turn does not prevent that unit from shooting in your Shooting phase or making a charge move in the Charge phase of this turn). You cannot use this Stratagem on a unit that disembarked from a TRANSPORT this turn.

EXTRA EXPLOSIVES
Genestealer Cults Stratagem
A batch of explosives, carefully acquired to avoid scrutiny from the authorities, is expended in one massive blast.
Use this Stratagem before a GENESTEALER CULTS unit from your army is selected to shoot or fire Overwatch. Up to 10 models from that unit that are armed with Grenades can throw a Grenade this phase, instead of only one model being able to do so (no more than five of these models can throw demolition charges).

DRIVE-BY DEMOLITIONS
The Rusted Claw Stratagem
The riders of the Rusted Claw attack with reckless verve, making close-range explosive attacks on the foe before speeding off in a cloud of flame and swirling dust.
Use this Stratagem before a RUSTED CLAW BIKER unit from your army shoots in your Shooting phase. Until the end of the phase, add 1 to hit and wound rolls made for attacks with that unit’s Grenade weapons. After this unit has resolved all of its shooting attacks this phase, it can immediately make a move as if it were your Movement phase, but cannot charge this turn.

You can not use Drive-By Demolitions in conjunction with A Perfect Ambush. The general FAQ forbids using Shooting Phase stratagems during “as if the Shooting phase” actions.

WARHAMMER 40,000 RULEBOOK Official Update Version 1.6 wrote:Q: When a rule allows a model or unit to take an action (move, shoot, charge, fight or attempt to manifest a psychic power) outside of the normal turn sequence, and that rule explicitly mentions to make that action as if it were a different phase of the turn structure to the current one, e.g. ‘That unit can shoot as if it were the Shooting phase’, do rules that are normally used during that phase (in the example this would be the Shooting phase) take effect? Is the same true of Overwatch attacks?
A: With the exception of Stratagems, all rules (e.g. abilities, Warlord Traits, psychic powers etc.) that would apply in a specific phase apply to actions that are taking place ‘as if it were that phase’. However, if a Stratagem specifies that it must be used in a specific phase, then it can only be used in that phase (e.g. you cannot use a Stratagem that says ‘Use this Stratagem in the Shooting phase’ to affect a unit that is Shooting ‘as if it were the Shooting phase’). For the purposes of this FAQ, Overwatch attacks are not considered to be attacks made as if it were your Shooting phase.

So no, you can't use shooting phase stratagems when you act "as if".
