So, you also worked a move like I did lol.
I heard that nowadays they carry small Lithium batteries and they don't know how blessed they are.

I have seen the new radios and batteries so much lighter than what we had in our day for sure

Yeah and I bet that the signal guys that go out with the foot patrols love all of the new lightweight stuff.
I presume that they can even us mobile phones now in contact situations lol.
