Let's collect some game play tips

Since I main the officer here are some tips;

First I am just going to disagree with a tip here;

• When using your Officer buff, remember that it only buffs in a cone in front op you. Wait until your team mates are in front of you before hitting that button!
  Pro-tip: When starting a new round and you find yourself in the front, do a 180 and hit that buff button, for a mass group buff.

Where in bold, there is no point in buffing your team at the start of a round, by the time they reach any conflict the buff will wear off and you then have to wait again for it to recharge before you can use it in a combat situation, wait until your team is in a strategical position and then try and buff as many as possible where the conflict is, I have saved many people from dying with this tactic.

Weaponry

• Blurrg-1120 with Improved Burst and Exploding Shot - The blurg is naturally a good gun, however adding the extra shot with explosive shot enables you to deal extra damage to other units around, this also helps in choke points allowing you to fire out plenty of explosive rounds, with this gun always aim for the gold/yellow part in the reloading bar as it allows you to get off more shots and inflict more damage without worrying about your cooling.
• SE-44C with Improved cooling and rapid fire - This gun is naturally a semi-auto however these mods allow you to get more shots down range, with the improved cooling you can let off the shots and the rapid fire allows you to get more rounds out in a faster succession to take out targets.   This gun also has decent accuracy and range, if someone is mid/long range ensure to fire single shot and when they are close/entering mid range use full auto (always full auto in choke points)

Useful Tactics;

• Squad Shield - This star card replaces your turret but helps so much in team based games such as death star on GA, if you are a rebel officer, drop the shield on the point, this stops you from being hit with blaster fire from flankers however requires work of other teammates to stop people entering the shield.
• Flashbangs - Flashbangs are perfect, they deal a little damage with the sub munitions and also blind the enemy, using this to your advantage is crucial, get as many of these at the enemy as possible for best results.
• Battle Command - Battle command is so useful, this allows you to buff your teammates for a needed health boost, don't drop it in random situations, ensure to get it when conflict is around, this then ensures they are able to get into conflict with as much of an advantage as possible.
• Don't try and be the hero - most officers do not work with teams, they tend to try solo the enemies, some officers are good enough but thats depending on your situational awareness, try and always move up with a team.
• Objectives - If you have a team, drop a shield on objective and you as the officer capture, the rest of your team defend you since they have more health & firepower.
