As modernization budgets are squeezed, the Army might have to be more selective about which units receive the most advanced equipment, a top officer said June 13.

Personnel and readiness costs are eating up the vast majority of the service’s topline, leaving only 18 percent for modernization, noted Gen. Daniel Allyn, vice chief of staff of the Army, during a talk at the Heritage Foundation, a Washington, D.C. think tank.

“Fundamentally it’s a math problem,” he said. “We have begun to look at … how do we prioritize delivery of capability to a smaller number of units rather than trying to spread the peanut butter” across the force.

That could lead to trouble down the road if the United States comes into conflict with a high-tech adversary, the combat veteran and Silver Star recipient acknowledged.
