DAO-12

The Armsel DAO-12, Protecta, or Striker to some, is the Tier 1 unlock for the Anti-Tank class in the game Battlefield 2. Unlike most unlocks, it is a completely different type of weapon from the defaults - the DAO is a Semi-Automatic, 12 gauge shotgun whereas the Anti-Tank soldier would normally get a Sub-Machine Gun such as the MP5 or PP-19. This means that it is more powerful than the default weapon, but it has a signifigantly shorter effective range.

Tactics
The DAO-12 Striker is a very powerful gun to have, being the second-most powerful shoutgun in the game, just behind the MK3A1 Jackhammer. With a magazine capcity of 12 shells and with a controllable ROF, the DAO is a great weapon for CQB. Be aware that the Striker has a very long reload time, as you will have to load the Striker's internal magazine 1 shell at a time.It will take about 2-3 direct hits with this shotgun to kill an enemy, no matter what kit they are.
