How can one resolve this? Phonetic alphabets. The goal of a phonetic alphabet is to give each letter a separate and distinct sound, thereby making it easy to tell what somebody is referring to. There are many variants of the alphabet, some of which use a few greek letters, but I prefer a system that avoids the greek alphabet entirely, since greek letters are employed to mark objectives in Conquest mode.
Here is my suggested alphabet, through L (12 letters, which is what you'll see once 12v12 games are added; Edit - I'm adding some alternative word choices):
A - Able - Alpha
B - Baker - Bravo
C - Charlie
D - Dog - Delta
E - Echo
F - Foxtrot
G - Golf
H - Hotel
I - Indigo - India
J - Juliet
K - Kilo
L - Lima
If you're in a command or support role and want to designate a target for people to focus, whether in chat or over voice comms, then try using these letter codes. This avoids things like calling for target Kappa and having everyone rush to the Kappa capture point while the enemy mech designated K murders you.
I've found that when I take the time to type targets into team chat, it pays off more often than not. It works especially well in high-tonnage LRM builds and other fire support mechs, since you often have a bit more time to communicate than in a mobility-dependent role.
Update 1
When calling targets, or when letting people know where enemies are, grid coordinates are invaluable. No scout should try to do his job without knowing how to call grid coordinates.
The map is arranged in a pattern with A, B, C, etc., and 1, 2, 3, etc. This results in grids labeled things like A2 and H7.
When communicating positions verbally, it is helpful to use a phonetic letter followed by a number, for instance Grid Charlie-Four. This can be things like "I've spotted a light moving through Kilo-Nine, heading toward Hotel-Seven." Or, "Focus Atlas Dog in grid Foxtrot-Four."
You can also use this to help your team stay together. "Move to Echo-Five and set up on the ridge line."
Edit - I only just realized my keyboard didn't input the 'h" from fashion. My apologies for the error.
Update 2
Another thing to remember is that the best way to drop an enemy is to make sure people are targeting the vulnerable or important areas of enemy mechs. Running a Target Info module and scouting for a group? When you find a target, call out not just its type, location, and code, but advise them on where to shoot.
"Atlas Echo in grid Foxtrot-Six. He's got a Gauss, so aim for his right torso."
"Cicada Charlie running up the Three column. Aim low and take his legs."
And so on. I like to focus on Gauss rifles, since they have a great chance to explode, and legs are a great target against anything that moves really fast, but you also need to pay attention to where enemies are injured already. If a mech has a Gauss on its pristine right torso and a breached left torso, then aim for the left side. If a light is running by and it's center torso is at red internals, don't waste time shooting for the legs.
To call out hit locations on the fly, try using these convenient short cuts:
Center Torso - CT
Left Torso - LT
Right Torso - RT
Right Leg - RL
Left Leg - LL
Right Arm - RA
Left Arm - LA
So a focus call might look like this:
"Hit Catapult Baker's CT, grid Charlie-Two."
