At Nova Prospekt, turrets are referred to as 'sterilizers' in keeping with the medical theme, and Combine attention starts with a focus upon an 'exogen breach,' presumably the antlions present in the complex, a large portion of whom are under Gordon's control.

It is announced around half way through Route Kanal that the 'judgment waiver' is in effect, stating that 'capital prosecution is discretionary,' and that sentencing is at their own discretion, effectively allowing Civil Protection officers to deal with humans as they see fit.

Instructions are issued to CPs to 'inoculate,' 'shield,' 'clamp,' 'contain,' and 'pacify.' His implicit citizenship (he could not be a legitimate citizen, as he has been presumed missing or dead for some time) is revoked due to his 'multiple anti-civil violations.' In this case, Freeman is addressed as 'individual,' and as such declared 'malignant.' When the Overwatch soldiers are introduced and the resistance movement is in full rebellion, she euphemistically orders the soldiers to 'treat' and 'amputate' rebels.

Freeman is progressively referred to as 'staph infection' and 'malignant'.

As proof of this, food credits are deducted from humans as punishment for what is termed 'permissive inactive coercion.'

It is announced near the beginning of Route Kanal that 'inaction is conspiracy,' thus encouraging local residents to turn in Gordon Freeman, who is just beginning his insurrection.

She announces the threat of 'permanent off-world relocation' to various people (usually Overwatch personnel, but this tactic has also been seen being used on citizens) as punishment for either mission failure or not informing on potential 'anticitizens.' Doctor Breen makes this same threat to Alyx and Eli Vance near the end of Half-Life 2 however, he is kept from delivering on it.

There are also similarities with the MFP dispatcher from the film Mad Max. Parallels can be drawn between the Overwatch Voice and the telescreen news announcer in the 1984 film version of Nineteen Eighty-Four, who serves a similar role and is somewhat similar to the Overwatch Voice in terms of voice.

Some of her announcements also display the coercive and violent tactics used by the Combine to ensure conformity. The voice uses a type of medically-inspired Newspeak to describe resistance activity in the context of a bacterial infection and treatment. Her disjointed speech, similar to that of telephone banking systems, and ability to apparently broadcast to more than one location at once suggests that she is an artificially intelligent computer system. Almost certainly artificial in origin, the voice will usually issue warnings of resistance infiltration or instructions to nearby units in a distinctive flat, clinical tone.
