Calling fellow city dwellers

[Hex]

For all I agree relying on a paintball marker as a defensive strategy is fated to leave you doomed, I do believe they could still be of some use. Such as someone taking a few unprotected hits to the face is going to know about it (especially if using reballs), while they are reeling from that it could give you the opportunity to follow up with a direct attack thus leaving your assailant permanently incapacitated.

They could also potentially be used for hunting small game. With the velocity cranked up they could act in a similar way to arrow blunt tips (alternatively known as bunny busters).

However the main reasons I would not consider paintball markers as a real option is
1) lack of real stopping power, yes it hurts like a bitch when your getting lit up but that won't kill you.
2) paintballs are made from biodegradable materials, meaning they have a shelf life. They also need to be turned regularly to prevent dimpling (reduces accuracy) and they need to be kept in a temperature controlled environment.
3) once your tank is empty, post SHTF your going to struggle getting refills.

Plus numerous other pro's and con's.
