[Milsurplus] SCR-536 for TD - Infantry comm

[Hue Miller]

"If, as will often be the case, a tank destroyer platoon is assigned to 
furnish direct support
to an assault platoon, the assault platoon should send an SCR-536 and 
operator to the
tank destroyer platoon during the operation......eliminating the necessity 
of transmission
of the signal through intermediate or higher units."

This is from a planning manual for attack on the Westwall, date Sept. 1942.
The TDs and big gun carriages used for radio, SCR-510 or SCR-610.
So when did the SCR-300 appear?  I suppose then it would have eliminated
any need for the SCR-536 in the vehicle and infantry platoons, for 
intercommunication?

BTW, this planning discussion, a Confidential report, includes this in 
Appendix F,
Alternate Chemical Plan:
"There is no moral or other reason why chemicals should not be used. We can 
be
assured that the enemy will use them; why not use them first?.....With 
favorable
winds, a large cloud will float 15 miles and be 5 miles wide, producing 
severe
casualties at 15 miles...."
