No Texting...This is Madness

Back in World War 1 there was no technology advance such as the ones we have now like cellphones and computers. Soldiers had to communicate with each other by sending letters that can take up weeks as for now we send texts and arrives in a sec. Sometimes it took so long that when the person gets the letter that soldier died in battle far long ago. This was an issue back than cause soldiers might ran out of supply and the only way was to write them a letter but by the time they get it theyll be long gone.
