you are underestimating rangers.. they have the same equipment the green berets have, and also have similar training. only difference is green beret operates in small group and are more trained in FID, while rangers are special forces used for clearing the way for infantry by their superior commando skill.
pls.. read this link.
The Difference Between Rangers and Special Forces | SOFREP
Equipment - yes.Training - Hell NO!!Practically the entire infantry of the US Army and Marines are extremely well equipped,almost equivalent to that of their Deltas.In an article I had been reading the other day,they had estimated that US Government has spent spent more than 16k USD for a single soldier or marine!!Can you believe that??No wonder even their regulars and as an extension,the Rangers and Force Reckon chaps are equipped better than most SFs in the world.But training - no sir,the Rangers come no where near the Berets or Deltas in terms of training.The difference between the probationary period of their training should be a proof enough.
