Intelligence support to UW forces All levels of SF operational detachment have some intelligence collection and analysis capability. Where appropriate, SF has two standing types of teams for intelligence augmentation, one for SIGINT/secure communication and one for counterintelligence. The SF SIGINT unit is the Support Operations Team-Alpha. Sensitive intelligence sources and methods may not be shared, although the information learned through these sources and methods will be shared. This is not a U.S.-only rule; while the U.S. may not share the details of technical methods such as SIGINT, the guerrilla government may have extremely sensitive information sources. During the Vietnam War, for example, the general U.S. rule was that Vietnamese allies could see only SIGINT information that had a SECRET or lower classification, and that did not carry the additional restriction "handle through COMINT channels only". Logistics Logistical support for all U.S. special operations come from two lines of command: USSOCOM provides "SO-peculiar support to SOF units worldwide." An example of SO-peculiar support would be providing Soviet-bloc ammunition if the guerrillas already have weapons that need it. The UCC commander, however, has overall responsibility for all joint support in his theater. The JSOTF logistics officer (J-4) is responsible for using the extraordinary procurement mechanisms legislatively authorized for USSOCOM, and making sure they are used appropriately. Note that dotted lines run from the underground and auxiliary to Navy and Air special operations units under the UCC Special Operations commander. These indicate that resupply might be brought in by sea or air, and the UW force will use other than the guerrilla force to receive them. Indeed, the guerrillas might make a diversionary attack to draw attention from the logistics or other vulnerable operation. SF commands, at battalion and above, have service detachments, tailored to specific missions. The SF support detachment has the responsibility for delivering supplies to the UW units in the field, by means specific to the situation, ranging from clandestine parachuting to armed conventional convoy crossing to the AO. Title 10 United States Code, Section 167, vests the SOCOM commander with the responsibility and the authority for the development and acquisition of SO-peculiar equipment, materiel, supplies and services—items needed for SO activities; for which there is no service-common requirement; or which the SOCOM commander deems as critically urgent for the immediate accomplishment of an SO activity. Supplies may be provided by the host nation or private companies within it,
