Are snipers and recon still valid in infantry battalions?

In our Army, Infantry battalions have a Recce Platoon which is made up of specially trained infantryman. We also have a Sniper Cell, under the administrative command of the Recce Platoon Commander, which is in reality overseen by the Unit Master Sniper (a Warrant Officer). Recent experience has seen us aim to grow the Sniper Cell into something bordering on Platoon strength, with the potential for an Officer to command it simply to keep the UMS out of the CP to do his job.

Our Armoured Regiments have mechanized Recce Squadrons and Troops. They are currently armed with the Coyote (LAV 25) although the government is looking at some sort of JLTV to replace them, which may cause a bit of a debate as we've become used to a decent fighting vehicle in the Armoured Recce Role.

Infantry Recce Platoons focus on Close Recce while Armoured Recce works on the medium recce. They can both do either, but really excel at one or the other. They both are pretty good at Combat Recce and work in conjunction with the Snipers to develop and prosecute targets.

Designated Marksman are something we are wrestling with at the moment - the idea hasn't been fully grounded yet. These are essentially "Sniper-lite" soldiers who recieve extra training on marksmanship.

At various times, different operations have seen these organizations under various command relationships with eachother (all grouped together, all seperate, etc, etc); I've heard various reports about both - I'd venture that personalities, more than anything else, make or break an effective combination of these various assets.

Our military has just released a new PAM entitled Ground Manoeuvre Recconaisance which rolls all of these into one and is actually quite good.
