The Combat Service Support (CSS) Automated Information Systems Interface (CAISI) 2.0, LINs A40443 and P99881, transitioned to hardware sustainment on October 1, 2014.
On the same date, the following hardware items transitioned for sustainment to the Communications-Electronics Command (CECOM) Life Cycle Management Command (LCMC):
- OL-701A/TYQ CAISI bridge module (CBM), NSN 5820-01-564-4845
- MK-2975/TYQ system support representative (SSR) accessory kit, NSN 5999-01-566-3094
- AB-1244/GRC-1 antenna mast kit, NSN 5985-01-616-6192.
This change also means that CAISI components are no longer available from the Product Director, Defense Wide Transmission Systems (PD DWTS). However, PD DWTS is still responsible for security accreditation and configuration management of the system.
Units, this also means you can now order replacement CAISI components through the Army supply system. Turn in unserviceable equipment through normal supply channels.
If your unit needs a complete CAISI system, first check to see if transfer of excess is available from other units or from an inactivating unit. If not, submit a requisition using the system NSN. OL-701A/TYQ, NSN 5820-01-564-4845, is the standalone system.
Note that NSNs for the OL-701A/TYQ and MK-2975A/TYQ are CECOM-managed (B16), except for the antenna mast cases. The antenna mast case NSNs are managed by the Defense Logistics Agency (DLA).
The SSR accessory kit consists of two cases. The black CBM transit case (Case 1) serves as a supply of backup spares; the SSR accessory case (Case 2) contains all the components needed to configure, set up and test the system in the field.
There is no NSN for the individual SSR accessory case. There are two options for getting it:
- Submit a requisition through the Army supply system for the empty black case, NSN 5895-01-625-1982, and the individual subcomponents; or
- Submit a requisition request for a complete SSR kit, NSN 5999-01-566-3094.

When it comes to safety, knowledge is the key to preventing accidents.
That’s why free Explosives Safety Assistance Visits (ESAVs) are offered to Army commands, installations or activities by the Defense Ammunition Center (DAC)/US Army Technical Center for Explosives Safety (USATCES).
An experienced ESAV team of subject matter experts from DAC/USATCES travels to sites to evaluate and ensure that local explosives safety procedures comply with AR 385-10, The Army Safety Program (Nov 13). Some areas that ESAV teams can assist with include:
- Standard operating procedures
- Explosives safety site planning
- Ammunition and explosives operations
- Explosives safety management programs
- Electrical explosives safety
- Fire prevention, protection and suppression
- Risk management
For more info or to schedule an ESAV, contact Jeffrey Stretton at DSN 956-8089, (918) 420-8089, or email:
Mechanics, inspect the coolant supply hose, NSN 4720-01-459-8689, for the personnel and engine coolant circulating heater (PECCH) in all of your unit’s Strykers right away.
Normal wear, excessive heat and acidic build up in the coolant can cause the hose to rupture. If that happens, anyone sitting at the commander’s station could be burned with hot coolant. Also, loss of coolant can cause the engine to overheat.
After the initial inspection, check the hose every six months for signs of leaking or damage and replace it if necessary. At a minimum, replace the hose every 12 months. The semi-annual inspection is being added to each Stryker’s -13&P IETM. That’s also where you’ll find the procedures for replacing the hose.
TACOM ground precautionary action message 14-021 has hotlinks to the updated PMCS tables. You’ll find the message on the TACOM-Unique Logistics Support Applications (TULSA) website at:
You’ll need your CAC and first-time users must first request access.
