Is what it says on the tin.
All seeing, all knowing stake in the ground.
Also known for being the heart of all the bitching that happens in the Army. There are 2 main types:
- Overt: Could be a sandbagged emplacement on high ground overlooking the area. Overt OP's could also be refered to as 'high visibility targets'.
- Covert: Inside the attic space of a derelict House, under a bush etc etc. Extended covert OP's usually meant you ended up pissing in bottles and shitting in placcy bags ... those were the days!
