Managing class VIII (medical materiel) on the
battlefield has always been a challenge, especially for divisional
units. Even with today’s modern technology, getting medical
supplies to the user is often a difficult task. To streamline
this process and empower levels I and II medical elements,
the Army Medical Department (AMEDD) developed the Theater Army
Medical Management Information System (TAMMIS) Customer-Assisted
Module (TCAM) and mandated that it be the system for ordering
class VIII at brigade level and below. With adequate planning
and command emphasis, TCAM can be a significant enabler in
getting critical medical supplies to the right place at the
right time on the battlefield.
in the field operates a TCAM
terminal. The terminal is plugged into the wireless
Combat Service Support Automation System Interface
(CAISI), which interacts with a Very Small Aperture
Terminal (VSAT) to provide Internet access.
What Is TCAM?
TCAM is a Windows-based, point-and-click application specifically designed
to allow providers of levels I and II medical care to research class VIII requirements,
submit orders via the Internet, and maintain an inventory database. (Level
I medical care includes immediate lifesaving measures provided by trauma
specialists with military occupational specialty 91W, healthcare specialist,
assisted by self-aid, buddy aid, and combat lifesaver skills, or by a physician
or a physician’s assistant at the battalion aid station. Level II medical
care includes all care provided by level I and adds laboratory, x-ray, dental,
and patient-holding capabilities. This level of care typically is provided
by medical companies and troops of brigades, divisions, separate brigades,
armored cavalry regiments, and area support medical battalions.)
TCAM enables users in units providing levels I and II medical care to access
information on the operations of their higher medical supply activities and retrieve
real-time data. Many features that were unavailable to them in the past are now
accessible. For example, TCAM can be used to—
• Obtain an up-to-date catalog that includes suppliers’ on-hand balances,
complete item descriptions, photos, and any available substitutes.
• Build stock record tables, which allow users to build, update, and track
their on-hand balances and dues-in.
• View and print the status of orders.
• Maintain an automated class VIII document register.
• Set up subaccounts for subordinate customers.
• View quality control messages that pop up automatically when certain
items are ordered.
• View the maximum release quantity of selected items and see if the items
People often assume that a special computer and equipment are required to use
TCAM. Not so; all a user needs is a desktop or laptop computer with a Windows-based
operating system, free updated software,
and any Internet browser. (TCAM Version 3.0 can

on “Site Map,” then on “AMEDD
Log Systems” and “TCAM 3.0.”)
TCAM is the fastest, safest, and most accurate way for medical units to process
class VIII data. It is currently being fielded to all units across the Army,
and it is already the standard in Kosovo, Afghanistan, and Iraq. In some areas,
medical supply activities use TCAM exclusively to request and receive class VIII
All levels I and II medical facilities are familiar with disk or hard-copy information
transfer, both of which are often called the “sneaker net.” Adding
Soldiers and vehicles to convoys to carry these data on a disk or in hard-copy
form exposes those Soldiers to some of the most dangerous areas on the modern
battlefield. Data can be transferred digitally with TCAM without putting a single
Soldier in danger.
is set up in a field environment (above). One main
CAISI system in a unit is connected to the VSAT (below),
and other elements that have CAISI systems can interface
the main CAISI to establish Internet connections.
So why isn’t TCAM the standard in every brigade’s
day-to-day business? After reviewing myriad after-action reports
from recently deployed medical units;
observing many units in training at the National Training Center at Fort Irwin,
California; and interviewing a number of subject matter experts, I found that
most of the levels I and II medical units in the current areas of operations
have at least tried to use TCAM. Some have had more success than others, but
most met with difficulty at some point. Problems occurred at the operator level
and continued all the way up to the division level. Through research and observation,
we have uncovered many of these problems. Some obstacles that seem to be common
to all units include—
• A lack of dedicated access to the Internet.
• Insufficient number of IP (Internet protocol) addresses available to
permit TCAM terminals to access the Internet on the unit’s local area
• Inability to transfer data because of network security protocols, or “firewalls.”
• Insufficient knowledge and training among operators to troubleshoot and
overcome operator-level problems.
Keys to TCAM Success
How can units overcome these obstacles and implement TCAM as the standard? The
answer to this question is twofold. First, units must plan properly and coordinate
all of the external requirements needed for TCAM to function properly. Second,
there must be strong command emphasis on getting units to comply and make the
system work. These two elements go hand in hand and must be present simultaneously
to be effective.
Several key areas must be considered when planning for TCAM implementation. First,
the user must have access to the nonsecure Internet. This can be done by VSAT
(Very Small Aperture Terminal), TACLANE (Tactical Local Area Network Encryptor),
or a commercial browser. Medical planners must make their communications requirements
known to the signal community early on so that TCAM framework requirements can
be factored into the overall brigade signal requirements. These requirements
• Providing TCAM terminals with dedicated IP addresses.
• Factoring TCAM terminals into the overall signal architecture.
• Locating TCAM terminals within the distance constraints of the category
V (CAT V) cable from the signal node (typically 100 meters). [CAT V cable supports
frequencies up to 100 megahertz and speeds up to 1,000 megabits per second.]
• Coordinating with the signal community to ensure that firewall ports
used for FTP (file transfer protocol) operations are open. [FTP is a communications
protocol that governs the transfer of files from one computer to another over
If medical planners can resolve these issues with the signal community, they
then can focus on the other contributing factor to getting TCAM running: command
When new and innovative systems such as TCAM are implemented, challenges and
friction sometimes impede progress and delay acceptance. As a result, units resort
to doing “business as usual,” which, in this case, means defaulting
to the sneaker net. When this happens, future attempts to troubleshoot the new
system are eventually stopped unless strong command influence dictates otherwise.
We see this trend time and time again with the fielding of new systems in the
military. Unless the command team decides to follow up and check on the implementation
of a new system regularly, the Soldiers usually get the job done in ways that
are most familiar to them—the old ways.
For example, when attempting to transfer maintenance data for the first time
by FTP, brigade combat teams (BCTs) at the National Training Center often struggle
with the process because they are not familiar with it. Problems occur, and they
default to the sneaker net. Although this method works, it doesn’t provide
timely and accurate data transfer. Without command attention, the units abandon
any attempts to use FTP simply because they don’t know how. It usually
takes a senior member in their chain of command, usually the brigade executive
officer, to enforce the “new brigade standard” and mandate that all
units transfer data by FTP. Eventually, as the units become familiar with FTP
and gain confidence in it, they use the FTP process efficiently to provide the
BCT leaders with accurate and timely information.
This training scenario undoubtedly is repeated when other BCTs attempt to implement
TCAM. BCT leaders are hesitant to mandate use of TCAM because it is new and unfamiliar
to the leaders and Soldiers. There is little command emphasis to
compel units to make TCAM the standard for class VIII operations.
Until recently, an automated class VIII system was not available to medical units
below level III (hospital care). However, TCAM is now the AMEDD standard, and
it is being used successfully by many units across the Army, especially those
that are deployed. Under the Army’s new BCT structure, TCAM will be the
tool used by brigade medical supply officers to manage class VIII stocks, so
knowing how to use it will become even more critical.
TCAM, like any new equipment fielded in the Army, has some shortfalls. However,
with proper planning and appropriate command attention to its implementation,
it can be a powerful enabler across the Army.
