- Cheap + reliable
- Parts for maintenance easy to come by
- Strong enough to mount an 50 cal in the back
You might have a mix of government owned vehicles, and ones rented from the local economy. You might be driving Hiluxes to work, and observing ISIS or partner forces using the same model as fighting vehicles.
Is the mounting problem even real? I’ve shot a 50 cal rifle unmounted and I’d venture to say it could be mounted to anything. It’s mainly for ergonomic / accuracy / rapid fire stability and doesn’t need significant structural support. You could probably mount it to an ATV if you wanted to.
