Just Add, Umm, Water

An anonymous reader writes "The US military has devised a way to ensure its troops in battle need never go hungry - with dried food that can be rehydrated using dirty water or urine. Bleh, but lightweight bleh." The original New Scientist story is available too.

Re:Tooth to tail?

[swillden]

Could you explain this "tooth to tail ratio"?

Sure. The tooth is the part that bites, and the tail is the part that drags behind. The tooth of a military force is the combat force, the actual fighting soldiers and their equipment. They're the people who actually push the enemy around and force the conclusion of the conflict. The logistical tail is the rest of the force, which exists to support the tooth and make sure it has everything it needs to fight effectively. Modern, mechanized military forces require incredible amounts of support. Ammunition, fuel, food, spare parts, intelligence, mail, etc., it takes a lot to keep them fully supplied, but they're also very fast and very hard-hitting when they're well-supplied.

However, while the tail is so crucial to the effectiveness of the tooth, it's also a liability itself. If the tooth is concentrated on taking the fight to the enemy, it can't focus on protecting the tail, which may leave the tail vulnerable to attack. Successful attacks on the supply lines leave the combat soldiers without supplies, dramatically reducing their effectiveness. The longer the tail, the easier it is to cut. Also, while well-supplied modern forces are highly mobile, the logistics chain is not, and the larger the tail, the more sluggishly it moves. This leads to situations where the combat forces can easily outrun their own supplies, effectively cutting themselves off. Last, all of the people and equipment who make up the tail cost just about as much money as the combat forces, but don't directly contribute to shoving the enemy around. The tail appears to offer no "bang" but costs a lot of bucks so for a given budget, a combat force that requires a smaller logistical tail is a larger, more powerful force.

The tooth to tail ratio, then, is a measure of how much of the force is dedicated to fighting vs support.
