Civil Protection is essentially the Combine's thought police in all urban areas on Earth, including City 17. Its officers are named "Metro Cops", while the spelling "Metrocops" is also used. "CPs" is mostly used by the Citizens and Resistance members to refer to Metro Cops. The entity uses the term "Metropolice" (the original term), and the subtitles use "MetroPolice". The Overwatch Voice simply uses the term "Protection".
Part of the Combine Overwatch, CPs are ordinary human volunteers who have "willingly" joined the Combine, either for more privileges, such as additional food, better living conditions, an increase in authority and status over others, or out of genuine sympathy and identification with the Combine's aims. As such, they are not bio-mechanically modified in any way, unlike the two other Overwatch units. Barney Calhoun is notable for having infiltrated the Combine by joining the Civil Protection ranks as an undercover Resistance member.
CPs wear white masks hiding their faces, with built-in vocoders to disguise their voices; these each contain a radio and air filters, and appears like a cross between an old Soviet PMG and a PBF gas mask. They also wear a combat vest, leather boots with a black-green uniform, an armband on the right arm, with "c̄17:i4" emblazoned on the armband written in a squeezed Impact font and "C17" in the back of the collar. For City 17's uprising, the Resistance has retrieved a high amount of Civil Protection combat vests for the Rebels, who wear them above their Citizen attire.
CPs are typically armed with 9mm Pistols and Stun Batons - they are known to beat unarmed Citizens at the slightest provocation; Barney Calhoun mentions being "behind on [his] beating quota". In more critical circumstances, they will be issued with Submachine Guns (which they fire from their hip), use Emplacement Guns, and are provided with fire support from APCs and Hunter-Choppers. Some officers are also armed with a deployable Manhack and/or Flare Gun to call for help.
CPs are almost always encountered in squads or teams (terms used by the Overwatch Voice), and will employ very basic tactics, such as covering one another and running to cover when injured or reloading. CPs normally attack in an aggressive manner, and will give pursuit to evading suspects. The Overwatch Voice also suggests that each squad has a particular leader. They are generally kept separate from Combine military units, such as Overwatch Soldiers or Synths, and stay in a policing role within the cities. They travel in APCs and Dropships and are often accompanied by City Scanners or Manhacks. They are also seen stationed on Combine Watchtowers from which they can fire flares to alert the other nearby CPs.
CPs heavily communicate with the Overwatch Voice over their radios; they are thus constantly fed mission objectives, rewards, reminders, and are directed to respond to certain incidents (such as the locations of downed units or other criminal acts). Civil protection do not communicate with each other like they once did as citizens, using instead complex procedure words. When a unit speaks to another unit, the unit being spoken to will say "copy" and then proceed on listening to the other unit's words. He will say "copy" to let the other unit know he has his attention. The unit that first started speaking will say the other unit's number code so the latter will know that he is the one being spoken to. The constant radio chatter usually gives away unit positions before they are visible. When a CP is killed, its radio emits a prolonged tone similar to that of a flatlining ECG, followed by the Overwatch Voice declaring the unit down, along with his last known location and orders to nearby units to respond.
Certain transmissions heard over the Civil Protection radios suggest that officers are rewarded with, in the words of the Overwatch Voice, "non-mechanical reproduction simulation" for good job performance. Another reward addressed by the Overwatch Voice evokes a "family cohesion" being "preserved", suggesting that a mission failure might cause trouble to the family of a Metrocop. Other radio transmissions imply that additional privileges are gained if a CP has its memory replaced, this being related to the promotion to Overwatch Soldier or Overwatch Elite by willfully surrendering more and more human features and characteristics. Another transmission suggest that CPs are provided with "anti fatigue rations" of at least 3 mg.
CPs are not as organized and effective as the two other Overwatch units, and generally use weaker, more basic weapons, and are not very accurate. They almost always work in groups, so when in a firefight with a squad or two, it is advised to hide as much as possible and shoot while they are reloading. As almost all of the combat they encounter is against unarmed and untrained Citizens, they will appear as being inexperienced with firefights against tougher, more competent opponents. CPs also do not carry out melee attacks unless they are armed with a Stun Baton.
In the early Half-Life 2 levels, a few pistol shots will kill a CP. In close quarters, a couple of hits with the crowbar will kill them. If they drop a Stun Baton in combat, it can be used as a battery for the HEV Suit. Later in the game, the best weapon to use against them is the Submachine Gun which can easily dispatch large numbers of them at once.
In the Canals levels, many explosive barrels are scattered on, under or near wooden structures where CP tend to stand. It is advised to shoot the barrels for more effective (and spectacular) results. Metrocops will also occasionally use the barrels as improvised grenades, rolling them to Freeman after igniting them. It is advised to shoot them while they are still rolling. CPs also often tend to throw themselves in the path of the Airboat or stand on breakable wooden structures, in a similar way to the Overwatch Soldiers with the Buggy in the Coast levels. This should be used as well for more effective results.

Behind the scenes
The Metro Cop unit was originally referred to as the Combine Guard (not to be confused with the Synth unit of the same name), which evolved into both the Metro Cop and the Overwatch Soldier. Much like the Overwatch Soldier in the final version, Civil Protection originally also had its elite variant, the Elite Metro Cop. Metrocops were originally to have other colors on their uniforms, such as red or yellow, and the right armband colored red. One version also depicts them with bright blue eyes.
Originally, the Civil Protection was to be named "Metropolice", name that survived in the CP entity, "npc_metropolice". Many Metropolice posters were to be seen around City 17, but were removed when the team thought that the Combine did not need to rely on subtle messages to achieve their ends. Three posters, designed by Randy Lundeen, are known: one involves the Consul, an early Citadel, Combine Guards, and the slogan "It's great to be part of the greater good". Two other posters, including again Combine Guards, bear the ironic slogan "They're here for you". Some of these posters are featured in WC mappack maps, when propaganda was still an important storyline tool for the team.
A Civil Protection headquarters building was originally to be seen near the Manhack Arcade, with above it the sign "C17 MP", or "City 17 Metropolice", in the WC mappack map "
c17_04" and its variants. In Raising the Bar, it is nicknamed "Cop Station", and was to be seen after and not before Kleiner's Lab. CPs were also to stand in Door / Guard Towers, hanging cabins used either to operate gates or guard an area. Moreover, they were to use early Combine Watchtowers near Sensor Gates, another cut Combine device.
According to Valve's animator Doug Wood, the Metro Cop went through several sets of animations during its development. None of them felt right until the team decided to give the CP a more bullying personality. Then Wood put a slight swagger into the CP walk and changed the chest posture to a more leading position.
In the Half-Life 2 leak files can be found several early Metrocop sounds, with the prefixes "mc1ans" and "mc1que". They mostly consist of chat between at least two different idle cops (as there are two different voices). Sometimes a bit hard to make out, these sounds include things like "You're in helluva a mood", "Watch yer mouth", "You expect me to believe that?", "Yep, this was definitely the best career choice I ever made", "I'm feeling pretty good about myself, ok?", "I wouldn't have kids even if they let me", "Supposedly we're getting a raise next week", "Your wife doesn't like me, does she?", among others. Setting Metrocops on fire caused them to start screaming, while they do not in the final game.
The Half-Life 2 soundtrack track "CP Violation", played during the chapter Route Kanal, refers to the Civil Protection and Gordon running against each other to Black Mesa East. One of the most fast-paced tracks of the soundtrack, it also has a shorter remixed version. CP Violation is also a concept in theoretical physics.
