- Communications should be limited to law enforcement chat.
Patrol officers will have no need to be in active comms with response officers and should be encouraged to be on seperate tasks.
- Rank requirement.
As a patrol officer they will have spending most of their time driving by themselves or at most with one other officer which means that they must be competent and knowledgable of the rules as they will not have a ranking officer watching over them.
Patrol officers should be allowed to use allow equipment their rank allows, maybe besides armored vehicles. While not responding to high priority situations, they may be put up against well equipped rebels and need to be prepared for that, especially since they will only be patrolling by themselves or in small groups.
- Lethal force
Lethal force should perhaps work similarly to level 2 security where they must only use it defensively where there is no other option. If there is a large rebel presence they should back off and inform the response force, it wont be their job to get into a situation where lethals may be necessary.
- Hospital Robberies
Like you said, hospital robberies can sometimes be hit and runs or large gangs but the rules on what you can respond to should be clear cut.
Perhaps a separate questline for patrol officers which is more relevant to their job. Would give patrol officers something to work towards rather than just aimlessly patroling.
Patrol officers should not be allowed to enter the kavala safe zone. I will always say no when asked for permission to patrol the safe zone, even late at night there will always be convoys and drugs runs which need to be found. Being in the kavala safe zones is one of the most useless things you can do as a whitelist officer, and being a patrol officer should be no excuse. Leave it to the pub cops.
- Involvement with the pub cops
Not to sure about this one. Patrol officers may help pub cops respond to kore gas sometimes but this may require close coordination. I feel that work with public officers should be the responsibility of police trainers.
The numbers of whitelist cops is a lot of the time very low and high priority robberies are usually fought with the bare minimum amount of officers e.g. 5-8 cops. After getting reamed by armed vehicles, 3-5 cops. This may be an issue if there are 3 people playing patrol officer.
