Massachusetts National Guard is headquartered at Hanscom AFB. Massachusetts National Guard is staffed by approximately 8,200 soldiers and airmen. Massachusetts National Guard is divided into - Air National Guard and Army National Guard units.
--------------------------------
Per the Mass Natl Guard website on Feb 5, 2015 - there are 6,285 Army Guard members at this time - and there are 2,173 Air Guard members. 80% of them are part time workers (meaning that they have regular fulttime 40 hr per week civilian jobs - and they serve as Natl Guard members 2 weeks in the summer, plus during activations, and for weekend training).
Mass Natl Guard has 45 sites in 38 communities in Massachusetts. The annual budget is $285 million (with $270M of that coming from the Federal government).
Mass National Guard can be used to backup local police - but US federal reserve forces cannot (Army Reserve, Air Force Reserve, etc) - this is due to the Posse Comitaus Act - per the FAQ at the Natl Guard website

February 2015
the Army Natl Guard is seeking Chemical Operations Specialists and UH60 Utility Helicopter Repairers
Chemical Ops Spclists get 10 weeks of basic training (basic soldiering) plus 19 weeks of chemical training
Helicopter Repairers get the 10 weeks of basic training plus 15 weeks of repair training
Chemical Ops openings are at Rehoboth and Brockton
Helo Repairer openings are at Westfield and Otis
This apparently answers one of my major questions - Mass Army Guard has Uh60 helos at 2 locations
