Manpack Loudspeaker Version IV (MLX4)

I felt it important to dedicate a post to this lesser-known piece of locally-developed hardware.

The Manpack Loudspeaker Version IV (MLX4) is a military loudspeaker. It is known to be used by the Civil Military Operations Group (CMOG) of the Philippine Army which developed the equipment used for Information Support Affairs operations.

Army Develops Manpack Public Address System 2013-08-18 (Armynews.ph):

Quote
FORT BONIFACIO, Metro Manila – Lt Gen Noel A Coballes, Philippine Army commanding general, watches the live capability demonstration of MLX4, a prototype portable manpack public address system developed by Civil-Military Operations Group (CMOG) in its endless quest to improve its capability in supporting Army troopers in the conduct of disaster relief, rescue and humanitarian operations. In coordination with NDRRMC, The army will dispatch several units of this prototype for further field tests and evaluation during actual relief and humanitarian operations in the field.
...
MLX4 is powered is by a 220 wattage of dual sourced batteries which could last up to 14 hours of continuous usage. It has a USB/SD port; two microphone inputs with tone control; a DVD player; an AM/FM radio; an MP3 port; and a siren that are all arranged in a backpack aluminum carriage with harness for easy mobility. The two units of 150 watts horn-type speaker could reach approximately one kilometer in an open terrain and up to more or less 500 meters in built up areas.

It is important to note that in 1997, Col Ferozaldo Paul T Regencia, who was then the CMO School commandant and now this unit’s CMO Battalion commander, initiated the creation of a Pinoy version of the man-packed loudspeaker. The very first prototype of its kind saw action in Brgy Lucapon South, Sta Cruz, Zambales then under the AOR of 68th Infantry Battalion. It was then followed by improved versions in 1999 which purposely became an indispensable tool during CMO-Psyops classroom instructions, practical exercises, and Civic Action Program conducted in Nueva Ecija.

The MLX4: Voice of Success 2016-11-06

At the end of the Zamboanga siege operations, the loudspeaker team helped government forces facilitate the surrender of more than a hundred MNLF rebels and the release of six civilian hostages.

...

During combat operations, loudspeakers have been proven to be more advantageous than other means of dissemination, such as leaflets and radio. Enemy commanders cannot prohibit their soldiers from hearing loudspeaker broadcasts.

Barely two months later, the MLX4 was tested in the field once more, as the loudspeaker operations team was sent to the heavily devastated Tacloban City in Leyte on Nov. 12, 2013 during the AFP’s Disaster Response Operations after the onslaught of Super Typhoon Yolanda.

The teams assisted in relaying messages of order and unity amidst the chaos and confusion brought about by Yolanda. The MLX4 helped in the distribution of relief goods by informing people when and where to line up, as well as impose discipline in those waiting for their turn to receive the goods.

...

The MLX4 has demonstrated its full potential in both combat and disaster situations, proving that, though it is not deadly, it can accomplish the Army’s mission.

As far as I know, these are the only images available online of the MLX4. I took them myself during the Philippine Army's 118th Anniversary display at Bonifacio Global City in March of 2015.

So I was watching a video compilation of footage from the 1989 kudeta and came across something that caught my attention (timestamp 6:05):



A loudspeaker system mounted on an A.L.I.C.E.-style frame. Probably a predecessor to the Manpack Loudspeaker.

There was another pack in the video with some other unidentified equipment as well. Likely a similar man pack speaker.
