Short answer -- No!!!
If used improperly, yes but...
a clankety clank and whop whop are real useful tools in the COIN tool kit...
FM 3-24 doesn't do a good enough job of saying this, but COIN does not mean you don't kill bad guys, and insurgent forces sometimes gather to conduct direct action against govt forces (especially if you don't have adequate firepower)....
From a strictly COIN perspective... I might not need an armor division in Northern Iraq, but an AR BN sure is handy...
