OK, got it: M15 antitank mines, medium density distribution protected by a mixture of M16A2 bounding and VS-50 pressure mines. Depth of mine barrier 100m from the first barrier system.
Minefield bordered to front and rear by anchored triple concertina razor wire with tanglefoot leading edges. Tripflares linked to wire front and back with both tripwire and command actuated firing systems.

Mutually supporting concrete protected machinegun positions spaced every 50 meters equipped with M240G 7.62mm machineguns 50m behind the rearmost barrier system. Machinegun posts provided with barrier area lighting system that can be employed to provide clear night time view of the barrier/engagement area.

I could add mortars to the mix - oh, OK M224 60mm mortars - Located 200m behind the machinegun post line and available on call by radio or landline.

You and your specificity...!
