JDAM-ER.

This is coolbert:

"The United States has provided the Ukrainian Air Force with Joint Direct Attack Munition-Extended Range (JDAM-ER) precision-guided bombs, allowing them to hit large-sized Russian targets, such as bridges and hardened fortifications, from long distances."

"A high number of American smart bombs are failing to achieve their objective in Ukraine, a Pentagon official told Politico confirming information in documents leaked by Jack Teixeira."

"The White House ordered The Joint Direct Attack Munition-Extended Range (JDAM-ER) be sent to Ukraine late last year. In March, the Pentagon confirmed the weapon was operational. While the document leaked by Teixeira is undated, it shows that Ukraine fired JDAMS on February 15 and 21."

Consider too the MILSPEAK contained in this classified document: BLUF, B/U, MAU-12, GWT, GMLRS, SAG-U, BDA, RUS, RFI.

Colonel Austin Bay correct. You need a glossary to fully understand the document. MILSPEAK a jargon very popular among those of the American professional military man guild.
