Here to serve, in West Bengal.

West Bengal runs from Himalayan tea estates to a tidal delta, and the guarding brief changes at every stage of that journey. In Darjeeling, Jalpaiguri and Alipurduar, tea factories and made-tea godowns sit deep inside estates on long unlit internal roads, Siliguri's wholesale markets, transport yards and airport carry north Bengal's freight, and monsoon landslides govern relief timings in the hills. Border crossings at Changrabandha, Hili, Mahadipur and Petrapole add truck parking and bonded stock to the work, with access restrictions and limits on night movement in the border blocks.

The western plateau is coal, steel and power. Paschim Bardhaman's Raniganj coalfield, steel plants and Durgapur's chemical and cement belt run continuous operations with coal sidings, ash ponds and material gates, where scrap and cable theft is constant, and Purulia and Bankura add thermal stations and long boundary walls on poor roads. On the coast, Haldia in Purba Medinipur carries a refinery, a petrochemical complex and tank farms under statutory perimeter and hot-work controls, beside a dock complex and the resort hotels of Digha and Mandarmani with sharp seasonal peaks.

Around Kolkata, density rather than distance is the difficulty. Kolkata's banks, courts, hospitals and Burrabazar wholesale blocks need gate, visitor and cash-movement control, Salt Lake Sector V and New Town in North 24 Parganas run IT campuses round the clock, and the riverside jute mills, foundries and engineering works of Howrah and Hooghly turn on three-shift gates and material checks in congested blocks. Further out, potato cold stores in Hooghly and Purba Bardhaman need cover when stock is most valuable, and in the Sundarbans blocks of South 24 Parganas sites are reached by boat and tide tables set the shift.
