Ironically, the 2nd Amendment is anti-militaristic. The idea is to prevent the central government from achieving a monopoly of force. That is why Lincoln had an army of only 26,000 in 1861, and that crippled by the resignation of many southern officers. To keep the capital from being overrun, he had to depend on the state militia of Massachusetts, which was sent by its government, the commander-in-chief of that states forces. Lincoln had called for 75,000 volunteers to put down the rebellion, and the war was fought by state militias on both sides, with a small number obtained by the draft and by the enlistment of freed slaves on the Union side.
