Infiltration protocol
- Infiltration protocol is a Decepticon modus operandi in the IDW Publishing portion of the Generation 1 continuity family.
The Decepticons in the IDW continuity, under Megatron's command, follow a carefully staged process of infiltrating and conquering inhabited planets. The staged conquest is highly secretive, with soldiers under strict orders not to break cover till late in process. When cover is finally broken, and open conflict becomes inevitable, Siege Mode is engaged. And if you're a native -- or an Autobot -- that's bad news.

IDW comics continuity
The Decepticon infiltration protocol has six phases, though not all have been depicted thus far.
Phase One presumably comprises the initial infiltration of a planet's society and gathering of intelligence. The Transformers have been on Earth for three years by the time Ratchet meets up with Verity, Hunter and Jimmy; Phase Two appear to be in its early stages by that point.
Phase Two involves the agitation of pre-existing conflicts and igniting "international hotspots". Frequently this is accomplished with facsimile avatars -- artificial duplicates of key members of the planet's native population, equipped to duplicate the original's actions, memories and personalities, but programmed to serve the Decepticons' interests. The goal is to get the natives to obliterate themselves, without the Decepticons' direct involvement.
On occasion, the Decepticons will encounter unusual resistance, and see fit to use a special protocol known as Mirror response mode, as they did when encountering the Avengers as Phase Two unfolded on Earth. Whether this MO is tied specifically to Phase Two is not known.
Phase Three - not yet described.
Phase Four - not yet described.
Phase Five - not yet described.
Siege Mode is typically initiated during Phase Five. Military protection of assets appears to be the goal of Siege Mode, implying that the Autobots and/or the natives are now making efforts to stop the Decepticons through straightforward military force; a massive above-ground fortress is typically installed on the planet and used as a base of operations. Secrecy is no longer a concern, as evidenced by the enormous and highly visible cliff-side command bunker that Starscream's crew erected in Oregon, as well as Runabout and Runamuck's flagrant and unconcealed attacks on Ratchet. Ratchet states that he has only seen this phase once before, though whether this is due to his normal role as a non-frontline combatant or because of other circumstances is not clear.
When Starscream's unit on Earth broke protocol by engaging Siege Mode too early in the infiltration, Megatron himself arrived on-world to investigate and apply some Decepticon-style discipline. Having put Starscream out of commission, he promptly downgraded the operation back to Phase Two.
As for Phase Six, well... Ratchet claims you don't want to know if there's a Phase Six. An aside comment by Springer ("I don't care if it's Phase SIXTY!") implies that the Decepticons have achieved Phase Six in the invasion of Varas Centralus: a state of open war on a devastated world. The flagrantly destructive and powerful Sixshot refers to himself as a "Phase Six kind of 'bot".
