Does that thing have top hatches so the passengers can provide flank security / RPG grenadier watch & suppression?

Never actually seen a SISU, so I don't know. Here is a Slovenian Valuk that seems to have all the hatches anybody could want.

Aside from the 20mm turret-equiopped versions, yes. There's a fold back troop hatch that can also allow the vehicle to double as an 82mm mortar vehicle or for the use of the infantry wire-guided antitank missile launch tubes so the vehicle is not entirely an *easy meat* proposition for enemy LAVs. And the side-folding hatches can be propped up in a 90-degree raised position to provide such exposed troops standing in the rear hatch with side flank protection from small arms fire.

You can't see it real well, but here's a shot of one with the guys standing in the open back hatch for just the reason you suggest.
