Reference the question on the abbreviation "res" on the medical roster. Reference TM 30-205 DICTIONARY OD US ARMY TERMS, 1944, page 233, under the entry Reserve, number 3 definition reads" soldiers and sailors not in active service, but available for call. Abbrev: res.

I would have to give it to you Rodger, you win the prize. I looked at the 37 MM but rejected it. Getting very rusty on my technical intelligence skills. Karl, when finding objects such as this an approximate bore size and scale are important. When I was on active duty I always laid an object of known dimensions next to the object being photographed. Not necessarily a ruler, I used a standard Swiss army knife, which I carried but any standard object will do.

Karl, I was way off on my previous ID. I assumed that the barrel is intact and measures 75 MM. If as I now suspect the bore measures out to around 47 to 50 MM this is the remains of a 47 MM type 1 AT gun with the barrel cut off, the trails removed and non standard wooden wheels attached. I am going on the two swept back plates on each side of the barrel, the remains of the elevating mechanism which crosses the barrel and the shape of the breechblock.

Karl, it is a 75 mm type 94 mountain gun with the barrel pulled back into almost partial recoil and missing the split trails.
The crazy ex paratrooper you met a the 2013 CDSG tour.

RE Remarks Apr 11, 2012 at 8:27pm concerning the lack of investigation Postwar on the sinking of SS Corregidor. As with many things were are trying to judge past actions by contemporary standards. The first thing is to acquaint oneself with the the beliefs of the day. The Spanish Civil War had just ended in 1938 and from this war came the birth of the 5th column, those prewar civilian operatives,local sympathizers, and infiltrated military. This growing fear was reinforced by the rapid fall of the European Countries to a real and greatly exaggerated German use of a 5th column. This made the us Army very wary of such a use by the Japanese and as quite a few stories attest a reality in the Philippines campaign. Thus the fear of a boatload of Japanese commandos seizing the SS Corregidor and conducting a surprise attack on Corregidor Island was not a paranoid thought. The reason that there was no investigation of the sinking was that no crime had been committed. The wartime rules in effect called for any vessel crossing the controlled minefield to be stopped at the guardboat, inspected, and escorted through the field by the guard boat. Any vessel not following the rules was to be treated as hostile and sunk by the mines as well as fired on by the alert battery, in this case the 3 inch Battery James. Thus Col Bunker was following regulations and there was nothing to be investigated. In fact if Col Bunker had rendered safe the mines he would have been guilty of dereliction of duty. As it was he would have been justified in opening fire on the potentially hostile vessel.

Reference the Cable tanks on Fort Wint. The purpose of storing the mine cables in salt water was twofold. The first was to prevent the rubber coating on the cable deteriorating. The second reason was to periodically monitor the serviceability of the cables by using a electrical meter to check the cable for electrical shorts due to cracks in the cable. All cables were laid out and cut to the proper lengths for the depth of each mine in the field, they were then placed on their drum and placed in the tank with both of the cable ends secured above the water. A tag was then attached which listed the individual mine number, group number, lot number of the cable. and test date.

I would concur with the ID of the post as Pipe MG mount for the 30 Cal M 1917A1 water cooled Mg installed as anti strafing weapons. There was however a possible misunderstanding of the Controlled Mine Field. There were no markers on shore, only land mines used Marking Stakes. As each controlled mine was planted each mine was equipped with a temporary numbered Planting Buoy. A bearing was then taken using the azimuth instruments located in the Mine primary and secondary station as was done in wartime fire control and the position of the mine with its number marked on the chart of the plotting board located in the Mine Casemate. When the position were marked the planting bouys were removed, leaving no marks on shore or the water to show mine locations.

Jim, I did not mean to sharpshoot you, it was just that as an old mortar man myself it just jumped out. If the crew was firing on caballo is you must have done it from the extreme tail which would have put the fresh water lake area barely in range, if the wind was right. Incidently I understand the reality of the very hazardous low level jump you made on Corregidor, I once made a similar jump from 450 feet, fortunately without anyone shooting at me.

As I was not there I normally don't comment on stories such as this, but in the word of my former organization, I have to throw the Bullshit flag down on this one. As a former soldier with about 33 years experience, and quite a bit of time wth mortars, a lot with the 60 MM this is impossible. I have measured the distance from the nearest point of Corregidor, Geary Point, and it works out to about 9.34 kilometers. As the maximum range for a 60 mm is 1900 meters the rounds couldn't reach Fort Drum with a typhoon for a tailwind. The only weapon system which the 11th airborne which could reach Ft Drum were the 75 MM pack howitzers with a 9500 meter effective range. A more viable target is Fort Hughes which by my calculations is out of range also. While I have at one time in a very bad situation extended the range of an 81 MM mortar from 4700 to a little over 5000 meters by adding a tablespoon of gasoline before firing, I would not try this with a 60 mm.

At the risk of continuing my boring technical briefings I noted a statement about the number of rounds which could be fired by the mortars before replacement so I thought that I would clarify and correct information on this subject. First the concept of tube life is based on trial firings and was arrived at using service rounds and max powder charges. The use of smaller charges at shorter ranges and the CI, Cast Iron, practice rounds caused considerably less wear on the tube. In annual practice firing the majority of the rounds fired consisted primarily of these practice rounds and thus the wear was less than the number of rounds indicated. While the I have no doctrinal evidence of the frequency, at certain periods the Ordinance Department would measure the actual as opposed to the theoretical wear on the tube and adjust the records of remaining tube life based on a wear chart. The measurement was conducted tru the use of a "Star Gage". The general rule was that the tube would be replaced when the number of remaining rounds on the tube dropped below the number of projectiles stored in the emplacement magazine. At this stage the gun tube would be replaced and, baring any other damage, the old tube would be sent to a ordinance depot in the US to have a new liner installed. It seems to be that a tube could be relined for at total of two more times, plus the original liner, prior to being scrapped. The projected tube life for the weapons present on the forts in Manila Bay is as Follows: 3 inch M1903 gun-2600, 6 inch M1905 gun-2600, 6 inch M1908 gun-2600, 8 inch M1888 gun-900, 10 inch gun M1895-800, 12 inch M1895 gun-350, 14 inch gun M1907-300, 14 inch gun M1909-250, 14 inch M1910-250, 12 inch mortar M1890-1500, 12 inch mortar M1908-1500, 12 inch Mortar M1912-1000, 155 MM gun M1918-3000. The Above figures were taken From Table 1, 4-210 COAST ARTILLERY WEAPONS AND MATERIEL, 1940. Due to the fact that Manila was so far from the nearest Ordinance Depot Fort Mills had spare gun tubes on site. As of 1928 the following spare tubes were stored on Corregidor: 3 inch gun M1903 1-tube; 6 inch gun M1905 -2 tubes; 10 inch gun M1895-1 tube; 12 inch gun M 1895-4 tubes; 12 inch Mortar M1890-1. I hope that this "Techie" post has not bored too may readers.
