The US Army's ability to maneuver rapidly on the battlefield may be over

• The days of rapid tank and infantry advances deep into an enemy's territory may be over.
• The US Army must be prepared more for fights that resemble WWI, an Army veteran argues.
• Any advancing force must move with a defensive bubble against enemy firepower, he argued.

Modern weapons have become so accurate and lethal that soon armies will not be able to maneuver rapidly on the battlefield.

Instead, they will trudge forward under the protection of defensive "bubbles" designed to stop drones and missiles. According to this vision, swift battlefield maneuvers will be replaced by grinding wars of attrition where victory goes to the side that has the most firepower as well as the most resources to replace losses.
