The Gulls hadn't won in front of their own fans since beating Macclesfield Town back in August, and their wait for a win looked set to continue when Keanu Marsh-Brown opened the scoring for Rovers in the 20th minute.
However, the host's response was sharp and swift as Tyrone Marsh turned home a cross from Andre Wright two minutes later, as linesman Andrew Rickett adjudged that the ball had crossed the line despite the best efforts of Forest Green keeper Steve Arnold.
Marsh netted his second of the match in the 37th minute, when he headed home a cross from in-stand skipper Courtney Richards.
With seven minutes to go, right-back Durrell Berry scored his first goal for the club when he slotted home after substitute Louis Briscoe had been denied by Arnold in the Forest Green goal.
Nevertheless, the Gulls weren't finished there as Wright burst through the Rovers' back line to score his fourth goal during his loan spell from West Bromwich Albion as United secured what was also their first league win since mid-October.
A few facts about today's game:
- The Gulls equalled their biggest ever winning margin against Forest Green Rovers - equalling their 3-0 win over Rovers in the FA Cup second round win in the 1999-00 season.
- It was the first time that United have won a game after conceding first since September 2014, when they beat Wrexham 2-1.
- Durrell Berry's 83rd minute strike was his first goal for the Gulls in either of his two spells at the Launa Windows Stadium.
- It was also the first time that United have scored four or more goals in a game since beating Bromley 4-0 in the FA Trophy second round on January 19th 2015.
