You generally don't get detached as an individual, but you do work alongside them (or tanks) on exercise as part of an OP detachment. You would work pretty much at the front line, rarely any further back than the company commander.
Apologies if this is patronising but I am assuming you are looking at joining as opposed to already in. For me working in the OPs is one of the best jobs you can do in the Army.
Lol, it was my experience that we spent more time with Infantry and tank/recce guys than we did with our own Battery "hods" when on excercise etc, we would be punted from pillar to post depending on who requested us..
