I remember this from PR and it's definitely one of the best features in the mod as it changed the gameplay. Especially building up a defensive position; razor wire, bunkers, HMG positions etc.
But anyhow I'm quite happy what FH2 is nowadays. Maybe it's not as versatile as PR but there are movable MG tripods, movable AT guns and movable mortar. Placing them right may do a lot of destruction and bring some little changes to each match played.
