Military training routes (MTR) above 1,500 feet are depicted on

Explanation

AIM 3-5-2 states that the IFR Enroute Low Altitude Chart depicts all IR routes and all VR routes that accommodate operations above 1,500 feet AGL; sectional charts also show MTR information. MTRs are low-altitude routes (generally below 10,000 feet MSL), so they are not a high altitude chart item, and IFR Planning Charts are not their charting product.
