As Bryant prepares to submit a planning application for the former Gurkha barracks site in Sandy Lane, more than 50 volunteers are poised to spring into action to whip up opposition to it.
They hope that with an organised effort, dissent will snowball and they can scupper the minitown plans yet.
If they fail, the group believes the new homes will have a disastrous impact the area, especially the roads.
"We will be leafleting the whole area so instead of having 750 objections to the draft development brief, this time we will have more than 1,000," said leading campaigner Jenny Radley."There really will be a huge public response to the application."
Campaigners fighting the minitown plan have now completed their own traffic survey of roads surrounding the site.
"We have just finished entering all the figures in a computer and now a member of the group who is a mathematician is going to look at the results," said Mrs Radley.
"We now have all the facts and figures and can prove that the traffic is a huge and dangerous issue."
Campaigners warn the local roads will not be able to take the estimated 2,000-plus extra cars that will be generated by the new development.
Mrs Radley said Bryant contracted out its own traffic survey and put down counting strips on surrounding roads between May 16 and 30.
"The first week was just before half term and the second week was a bank holiday so if they think that is representative of traffic movements at peak times then we have the facts and figures to challenge them," she said.
Campaigners are also concerned that local services will not be able to cope with the 3,000-plus new residents.
"The schools and health centres are full and there are no more parking spaces left at the railway station," said Mrs Radley.
"The impact that this application will have is huge — it's going to affect everyone and they are not even half way through building Elvetham Heath.
"We are hoping to arrange meetings with Hart planning officers because we do not think we have been properly involved in the process.
"We have got some very good people out there who are prepared to put in a lot of time and effort and we have proved we are an active and responsible group that must be taken seriously.
"We need to provide a balanced view rather than rely on contractors' reports."
Mrs Radley and her friend Soo James, who organised a public meeting about the minitown plan in February that was attended by about 500 people, have also got the backing of their MP James Arbuthnot after seeing him at a recent constituents surgery.
He has vowed to call for a proper traffic assessment carried out by Hampshire County Council and has taken up the issue of the Public Safety Zone (PSZ) for Farnborough Airfield, which crosses the minitown site, with the Department for Transport.
"The PSZ goes right over the high density area of the QE barracks — it really beggars belief," said Mrs Radley.
Campaigners will also be keeping a careful eye on the site after becoming alarmed that lizards and snakes may have been removed from the green fields.
Defending its timing of the traffic survey, Bryant Homes said in a statement: "(We) understood that a local community group was planning to undertake a traffic survey adjacent to the QE2 (sic) site at Church Crookham on one day towards the end of May.
"In order to mirror the results of this survey and to counterbalance any misinterpretations of traffic flow in the area, Bryant Homes commissioned an independent body to monitor traffic flow over a two week period at this time.
"The timing of this survey was based purely on when it was understood a local community study was being carried out.
"This study was completely separate to an in depth traffic assessment carried out in the area some four or five months ago, for the purposes of planning requirements."
