Simple enough, a mast-mounted TGP for the AH like what a Kiowa Warrior uses.
The purpose is to offer a slightly more user-friendly alternative to the existing mast radar for firing at targets from cover. It would allow from-cover loft attacks for laser guided hellfires and APKWS with the downside that unlike with the radar-assisted optical variants and GPS-guided rocket-assist glide bombs, you'd have to keep the target lased the entire time. UI-wise, just have an OSB for switching between the forward sensor and the mast sensor.
Pros:
More user-friendly target designation than the existing AtG radar framework allows
Based on an existing sensor system both in-game and IRL (Should be fairly easy to implement from a development standpoint as all the code is already there)
Increase versatility of two-seater play as this would be considerably more difficult to use correctly flying solo than the radar because momentary loss of laser LoS is all it would take to foul your shot.)
Cons:
Not as useful solo due to the split attention between position keeping and sensor management
It's ultimatley going to be a superior system to the radarin mot circumstances unless-and-until we get a QoL update for the radar or weather conditions that require the use of radar over optical sensors
